Much better than the teacher I hated point slope form just cause I didn't understand it now I'm like "what.. This is easy?? "
Same
Thank you so much, you always explain these lessons better than my algebra teacher.
Thank you my teacher always takes multiple classes to explain it and somehow I understand less and less
MR. Organic Chemistry Tutor, thank you for another excellent video/lecture on How to Graph Linear Equations in Point slope Form in Algebra. These tools/concepts are always needed in Mathematics.
That's why I couldn't solve it! The signs fooled me!!
Thanks so much dude, now this is how they need to make teachers teach it!
This really helped thanks!
What could I do if the slope was 1 or -1? And how would I move 1 unit to the right/left, where did that come from?
Since the rule is y - y1 or x - x1 etc, if the original number was negative, it was say y + that number because subtracting a negative number is essentially just adding. This means that since it is a normal subtraction sign the original number is positive. Hope this helps.
Oh, I get it now. Thanks so much 😃
@@cwebbi I can never understand this lesson im trying until now for around 3 hours
Thank you so much
This save my left I have a test tmr and i didnt understand nothing this week but thank u
Omg thank you so much this is so easy
OH YOU ACTUALLY SAVED MY LIFE
very helpful, thanks
Thanks a bunch
Thank you so much man
How do you graph y = -1/2 x - 3? Does the coordinate is (0, 3)?
thanks man.
you are my hero
doing math homework using this
What is the M is 3/5? How would you do that?
Question: so if I was given a slope and the points I can just graph them? ‘Coz I was taught that I have to solve them with point slope formula and start once I got the slope intercept form.
Graph it and then write it in the
y-y1=m(x-x1) format
This guy just simplifies everything. Thank you Sir 🫡
Thanks
I love u sm
why do u flip the signs ? reciprocal of x1 and y1
listen, in the original equation, the y's and x's are subtracted always : (y-y)=m(x-x).
if you have a point that has a NEGATIVE number like (-8,-9), the subtraction sign in the equation will make it positive or addition.
for example:
( y - y ) = m( x - x ) and ( -8, -9 )
(y-(-9)=m(x-(-8) because the points are (negative) - (negative) they will make positive: +
so, (y+9)=m(x+8).
If you want to graph it you'll need the actual points, which are (-9,-8).
so you will reverse the sign (if positive) into negative
and, make the negative into positive (if negative) if you need to graph it.
@@unremarkable9098 Thank u so much. I was getting worried if I was going to forget that during a test of mine, u just cleared up all that confusion/worry
Thanks
Do you have to always have 3 points or can it only be 2? Bc my next point goes off the graph.
3:49
Genius
What if slope is only written as - ?
Y+5= - (x+3)
Then it would be -1x or you would factor out the negative
Don't you have to distribute 3/2 to (x+4) then subtract 3 from both sides ???? so you end up getting y=3/2x +3??? someone Im confused.
The one ur talking abt is slope intercept form which is y=mx+b (since y=3/2x+3 is y=Mx+b, 3/2 is slope and 3 is the y-intercept) but the video is talking about point slope form which is
y-y1=m(x-x1)
There’s also standard form
Ax+By=C
I hate geometry so thanks for the help
this is not geometry...
its algebra
Suki Longtime Well my teacher taught us this I my geometry class so...
For the first equation why did you skip one point on the x-axis i thought we had to skip 2
Because the slope is 2 we can make it 2 out of 1 or 2/1
You also have to remember rise over run, so you go up 2 and over 1
1:11 where did the five come from??
so since the slope is 2 and isn’t a fraction you would go up 2 and go to the right 2 if the slope was 3 you would go up 3 and to the right 3 if that makes sense i hope this helps
I spent so much time on my assignment that it only took me 1 min to understand it smhhh
I love you
YESSIR
Something went wrong here
Sorry i forget the rise 3
Why cant I watch the video?
thank you. Aleks sucks at explaining the steps
Didn’t help me at all
