@Raymond Huertas okay so basically from what i understand, you have to plot all the points first to get a scatter plot. like usually there is a table with point values, so you put all the points onto the graph to get a scatter plot. Then the second step is to get a ruler like he said in the video and then get like a straight line in the middle of all the points. So, to find the line's equation find the two points on the lind one at one end of the line and one at the other end of the line. then use the equation: y1-y2/x1-x2 to get the slope which is m. the whole equation at the end will be equal to y = mx + b. So, whatever you got for M you can plug it in. Then you have to find B the y-intercept. You can do this by extending the line to touch the y axis and see which point it intercepts with then you will have the final equation no need to find x and y just need to find y-intercept (b) and the slope (m). I hope this makes sense if not I'll try explaining it again in another way. Also, anyway else in the comment section feel free to correct me i might be wrong.
@@davidsonmusicofficial no I know how to do it. Its just what we have to do that is so hard. Like its thing called ixl and its a literal nightmare. You miss one question and you have to do 3 extra questions
thanks, Mario! I had recently lost my math binder and it hasn't turned up. Unfortunately, that binder had all of my notes and we have a test coming up on this subject. This helped me a TON! I liked the video and I subscribed to your channel. Once again, thanks!
You’re welcome Chase! Hope you find your binder but I’m glad my video helped you! Good luck on your test...report back if you want and let us all know how you did. Thanks for being a part of the channel!
@@MariosMathTutoring Well I did very well on my test, thanks to this video. I got just about every question correct. I still haven't found my binder but this channel helped me out. Thanks Mario!
This helped quite a bit! No matter how many times I read it elsewhere, I just didn't get it. Just wondering, how did you get from a + in the beginning to a - in the end? Wait, I think it's cause you made -13/3 not negative?
thank you so much to all the teachers teaching online.... because if it wasn't you... I would have lost faith in teacher's actually explaining the logic...
When i am plotting the line of 'best eye fit' is it necessary that i have to begin with origin ? And is it also necessary that my points are equally distributed from top and down ?
When we are just ‘estimating’ the Line of best fit you want ‘approximately’ half the points above the line and half the points below the line...and the line doesn’t have to go through the origin...hope that helps Ayaz!
I have a math final in less than an hour and the part where he showed how u find the b helped me soo much i forgot how u find it and was confused how u plug it into y=mx+b
Y'all, pray for me. Been debating on asking this girl for her number at work. She ended up asking for my number so I could do her work for cash. If everything goes well, Imma make my move
This involves guestimating and approximation. Maths isn't about guessing and approximating however. If anyone wants the real formula for finding the slope of a line of best fit it is m(slope) = (n * sum(x*y) - sum(x) * sum(y)) / (n * sum(x^2) - (sum(x)^2) Where m = slope, n = number of data points, sum(x) = the sum of all your x values added together, sum(y) = the sum of all your y values added together, sum(x*y) = the sum of all the values you would get after multiplying each x value by its corresponding y value sum(x^2) = square each X value, then add together all of those values sum(x)^2 = add all X values together, and the square that sum. This will give you the EXACT slope of a line of best fit without any guess work or approximation that will give you an incorrect slope based on guesswork. to find your Y intercept to the exact decimal value also you can use formula b = (sum(y) - m*(sum(x))) / n where m = the slope value you just worked out above. And this will give you a mathematically calculated y-intercept value that isn't based on 'guessing'where the line should run and intercept the y axis.
Good question....when approximating the line of best fit we are just picking two points such that the line comes roughly as close to the other points as possible with some of the points above and some below the line....it doesn’t have to be the first and last points...this is just an approximation....for an exact line of best fit you can use the linear regression feature on your graphing calculator.

How do I decide what number goes for y??
you use the Y coordinate for one of the points on the line
what if the points are not on a Cartesian plane but on a scatter plot
what do i do if theres only one point that lines up on my line.... do i redraw it and try and force it?
Thanks to you I won't be failing science
Glad my video helped you with your science!
5 could also be used for y right?
if when doing the thingy and 1 in 4/3(1) was a bigger number would you multiply the fraction by that number
I have a math test tomorrow about this and I’ll tell you if I pass tomorrow
Ok good luck on your test Sergio!

do you just put random points or how to you find them
Generally they give you the points or if you are running an experiment you generate your own data points.

@@broingup1239 anyway did you learn how to use the method i posted for an accurate slope and not a guesstimated slope?
@@abowden5079 nah im too stupid to understand that
thankyou jhonny sins for the explanation

Who's watching this from OHS
When finding the line of best fit, should my line start with the first point on the graph and go up from there?
Good question....when approximating the line of best fit we are just picking two points such that the line comes roughly as close to the other points as possible with some of the points above and some below the line....it doesn’t have to be the first and last points...this is just an approximation....for an exact line of best fit you can use the linear regression feature on your graphing calculator.
what if I chose a point in which most of the points on one side are on the edge of the line but the two sides of the line aren't balanced?
