Learn how to solve a system of equations by graphing

- Опубліковано 3 сер 2024
- 👉To solve a system of equations means to obtain a common x-value and a common y-value that makes the each of the equation in the system true. To solve a system of equations by graphing means to obtain the point of intersection (if any) of the graphs of each of the equation that make up the system. To graph a linear equation, we set the equation in the slope-intercept form and then graph the intercept and obtain the line using the slope.
The point of intersection of the graphs of the equations that make up the system is the solution to the system of equations.

I was literally just gonna search it up, can u un-resigned and come to my school we really need you
@@irony8345 "ok"

Wow theese math videos from 2012 really come in clutch when you don’t pay attention in class😂
Even when you do pay attention in class... I'm doing flvs myself and guided notes do virtually nothing
Exactly 😅
Yep
Yup
Math is like my brain being rapped
11 years later, these videos are still helping students. Thank you.
Real spill
👏🏼👏🏼👏🏼
You did a better job than my own teacher.
happy to help
Wafaa Alhalabi I had a sub and she gave us this worksheet
are you sure you just don`t pay attention in class
Walla such a bad girl
literally my teacher doesn’t even teach
This video is ages old but this man single handedly just saved me from hours of stress
Samee tmw I have an exam and I cant understand anything until I saw 2 of his videos total is 9min and I understood asap
yea
True that
You really helped. My teacher is really strict and likes to call out on me, so this time I'll be prepared to answer.
awesome! love it
Lol
Good luck!!!
Abrea Kirkland happy 100 likes
Screamed "My man" and hit my phone when i understood this.
lmaoooo ik he's great
As someone whos taking accelerated math, this is the first unit that has had me lost and confused. Brian, I have a great math teacher, but these videos are so informative and laid back that I feel like I learn in 5 minutes what would take me 2 classes to learn normally. Thank you, you have saved me from systems of equations
why did this sound so deep 😭
fr🤣@@meeribali333
ur so real for this but my teacher is awful sooo🥰
I am 35 and had to take a Math course to finish my degree. I credit the passing of my course to Brian McLogan. Could not have done it without his videos and clear explanations. Thank you!!!!
you my homieee thanks for teaching me the whole semester in one week
you are very welcome! happy to be able to help hoimee
@@brianmclogan Dudeee your a life saver 9 years after u posted this video,!!!!
@@thelegoguy5199 ^^^💯❤️
Thank you my teacher spends half the class meditating
I pay attention in class and still understand nothing swear these UA-cam teachers are the cream of the crop
Thank you so much for your channel and taking the time to teach step by step. It has been a rough year with our teacher not actually teaching and just giving us the work. I learned a whole standard in less than 5 minutes when it usually takes me the whole week stressing trying grasp the content, still not knowing if I understand it. Thank you so much for continuing your channel
Thank you for all your posts. My specific teacher doesn't do lectures....
He's more Iike "Here's a text book. Good luck..."
😂
I learn more from you then my teacher thanks to you I'm going to pass my exams
This guy has just helped me save my grade
No one:
He is always telling his students in other words to stfu🤦🏾♂️🤣
i only watch your videos for math so i really appreciate your content given the fact that I've gone around with several tutors and obviously several channels but your explanation are succinct and straight to the point. Thanks!
really appreciate it Brian and very happy to be able to help you out!
This is so helpful! I have been learning this in school, but I was having a lot of trouble coping up with my class, so I searched on youtube, and I found the easiest ways to solve systems of equations!
Watched 3 videos before this and he explained everything in a much more simple way. Thank you so much!
anyone heard the word “sweet” at the beginning it sounds creepy
nope?
Brian McLogan dude i heard the word im not deaf it was like “SwEeT” but in a creepy voice
I heard it 2!!!!
It wasn’t creepy, I thought it was funny😂
😂😂 yeah
Thank you so much! My mylab lesson left me with more questions than answers so I went looking for someone to breakdown every step and found you.
ur a literal lifesaver!!! the way i was being taught wasn’t working for me but this is wayyyy easier!!! definitely gonna pass my final now!
well done! you did better than my teacher! 👏
awesome! happy to be able to help
Furry=yucky
@@joedigger8796 hey be nice like the guide line says
Honestly he explains it so clearly and I can actually follow along and learn
my teacher said this lesson is the hardest lesson in our text book and you helped me understand it better than my teacher who teaches half the lesson and moves on to the next lesson
you are very welcome! keep up the hard work
This helped me a lot but I’ll probably forget it 😅
You think there’s people In the room with him, or he’s trying to make it look like it? Bc if it’s just him in the room he got me fooled
i heard ppl talking in another video
Wow! I used to struggle greatly with this subject and know I'm getting straight A's thanks to your videos.
This helped alot. My teacher tho says that I have to use:
Elimination
Substitution
Graphing
Comparison
U helped me with all of them except comparison...I'm dying
Thank you I had never really been sure how to do this and now that I am having to relearn it all I am so lost and this helped me alot.
In college as a 29 year old going on 30. Man you are a beast, love you a ton. My math professor doesn't suit my learning style so these videos are the one thing keeping me from dropping or failing the class. Mr Badass McLogan!
My teacher takes like 20 min to teach this but u take 5min to explain I’m impressed. Also u explains this so much more easier for me cause I’m not that great in math is this really helps!
I love your explanation, however, it would be better if you had a grid on your whiteboard, because with what you drew it looks like the solution is the point (-1, -3) but the true solution if you had a better grid is really (-2, -5). However, I really loved your explanation! Thanks for posting your work!
good point, I should bring that up to my principal
You made the concept so simple and easy to understand,thanks alot
Hello anyone from 2020 this hw for school cause of earthquakes
No there’s a global panemic now that’s why I’m at home 😂
Tf you mean earthquakes
@@isaiahrogers4940 Just before corona were I live we had earthquakes
Thank you so, so much! It took me a while tho but I'm still glad that I got it! Thank you very much!
I still dont get it
dude, your channel is a lifesaver
Thank you I love u
You made my test so easy I got 100
Thank you so much, I was so stressed on this practice test and so far 6 of ur videos have helped me understand
this one video taught me more than my math teacher taught me in 3 months
You really helped me a lot thanks 🙏🏼 now I am going to school I have a math final exam 🤷🏻♀️😫❤️wish me luck
OMG ME TOOOOOO WTF
You answered on the exact question I was trying to get. Thanks!
awesome! you are very welcome!
If only teachers can explain stuff like how you did. I’m taking pre calculus in 11th grade and my math teachers can’t even speak English(not literally). I’m just look back at this for sat study. Thanks for your help.
you are very welcome!
Exams are coming up and this is very helpful, thank you!
that makes so much sense now!! My teacher doesn't explain very good and she confuses me ALOT!!!!
happy to be able to help you out!
Everybody: wow this makes so much sense what clutch
Me: he has really nice handwriting
Can you be our math teacher?
Tori Walker-Gulley no
Right?
Thank you for the lesson! Homework is easier now! Thank you!
you are very welcome!
Thank you, you have everything I hope to find in the Internet
Thank you for helping me with my worst subject! Yours truly, the English and history geek
Thank you you just saved me from so much stress lol
advanced math final today😪 wish me luck thanks kind teacher
This Video was an eye opener!! Thanks so much!
Lmao my teacher shows us your videos from time to time 😂
I would love to shake this mans hand some day. If he only knew the time and frustration he’s saved me 😂😂
I've been stuck all night on an assignment due tomorrow at 7am, I can finally go to sleep thank you
I've been stuck all night on an assignment due tomorrow at 7am, I can finally go to sleep thank you
thank u!! i have a hard time focusing in math class and this rlly helped!
Thank you for this video it helped me not have a late assignment.
Thanks a mega ton, I literally watched for about a minute and realized my mistake
This guy is a great teacher.
Explained more than my teachers explained to me during this whole quarantine
Thanks
Sir I am from India and your the best
Whenever I need help with math, I watch you.
I appreciate that!!
Thx I really needed this, i could not understand how to graph it at all in math class
It has been 11 years since this video has been uploaded although it is still not forgotten and helpful
not the hero we deserved, but the hero we needed.

*SHWET*
👍
Thank you there are only 3 people in my class and ive always seemed like the dumb thanks to you im am going to fix that:)
omg this really helped me I got my semester exam in a couple of hours and I’ve been up till 2 studying wish me luck!
Chloe ! Hope you do good,even thought it’s almost.a year
Uh i am learning this in grade7
INCORRECT. The intersection is (-2,-5)...never use the graphing method to calculate an intercept point, put them in y=mx+b (y#1=3/2x-2 and y#2=2x-1) then solve for x using (3/2x-2=2x-1) which gives x=-2, plug that into both y='s (3/2(-2)-2 and 2(-2)-1) and both y's will =-5...which is where they cross if you plot it on graph paper.
there is nothing wrong with using graphing to calculate the intercept point, there is everything wrong with not making sure you have accurate graph on graph paper, I should have recognized my error and checked algebraically so thank you for noticing and posting. Will pin your comment so others can see.
@@@brianmclogan yes, it is your sloppy graph which let you down, and I agree: graphing is perfectly fine, especially for integer x- and y-coord. solns.
Brian McLogan but is the answer u did still right
@Antonio Camurugy Notari well said
shut up nerd
I have a question
What if your Y-intercept was a decimal would you turn it into a fraction or just graph it less than 1?
Eu sou do Brasil mas vou falar na sua língua agradecendo muito. Thank you very much helped me so much my friend
Feliz por poder ajudá-lo!
Thank you mister good job🖤
my teacher taught my class this in one day and tested us on it the same Friday after teaching new things everyday and expected us to learn it in one day.
- he's a bad teacher that gives us an example without steps
Thanks Bri-Man, you're a real gem. Reading it from my e-text for online class just isn't the same, yknow? Mr. McLogan helps the people GET IT.
Who is watching this to do their homework in 2021
me just 2023 lol😂😂😭
Thanks Brian!! This helped me a lot!! You got yourself a new subscriber!
happy to help and have you
with midterms exams coming up this was so helpful tysm😭😭🙏🙏🙏
this really helped my left ear
Thank you for explaining.
(3x-2y=4)-(4x-2y=2)
-x=2
x=-2
(6x-4y=8)-(6x-3y=3)
-y=5
y=-5
Thank you so much, I have a test on this tomorrow and I missed a week with strep throat so I missed this hole thing in class
Same, swallowing knives was an experience to remember...
I know you already helped me with my homework, but help a brotha out and vote for me in 2020.
happy to help! no problem
Brian McLogan I’ll be in math class soon, I’ll give you a problem and you can solve it for me 😂
yea sorry, barely able to keep up with what I am currently teaching at the moment
Is 2020 already
Thanks for the Help, I get confused when it comes to using x and y intercepts plus graphing. My graphs always end up either parallel or onesided.
just keep working at it
So helpful thank you!
You’re a lot better at math than rugby...lol. Helping my niece w math and ran across your videos. Keep up the good work bud
Haha no shit!! Love it man
This is so helpful thank you
GlitzyGrace hiii
Although the answer is incorrect, this video helped a bunch bless ur soul
Thank you!
Ser. Thank you
You hepl me solve my assignment well
Thanks you just saved me
god bless this man he has saved me countless times, my teacher has a very strange way of teaching where she actually doesn't explain how to do the work at all, and you always seem to be able to help.
Bru this guy makes so much sense
You just saved me on my test😳😳
At 1:15 I don't understand how 4-3 equals 3 x and at 1:15 why did you decide to subtract Y instead and and what would happen if you decided to do it the other way and why would you need to divide?
Caveman Spongebob when you subtract 3 from both sides, you don’t necessarily solve the problem. You write it as the number that your subtracting from and adding/subtracting to the top number. For example, if your line is 4x + y = 15, you would subtract 4x from both sides and right y = 4x + 15. Confusing, I know.
Thank you so much. This is just like what I learned in class but so much more simplified when you explain it. A lot of people might not say it, but this video is a real lifesaver for them. This is definitely getting a thumbs up from me and I will recommend this to anybody who needs help on this particular subject.
Appreciate it, so glad to have been able to help you out!
This man is keeping my grade at an A
Thanks a lot this helps a ton
