I cant describe how much the guy in this video has saved my life. he explains things in the least complicated way possible. the different colors for the variables are perfect for understanding whats in the equation relative to the physical slope on the graph.

Another way to look at it is y - y1 = m (x - x1)

I have a math test tomorrow and this was the last subject I needed to cover. Thanks, Sal.

OH. MY. G*D! IT TOOK ME 1.5 WEEKS OF WATCHING SO MANY VIDEOS. Watching this alone couldn't get my brain around it I think it was just too many subjects at once for me. THEN FINALLY a combo of a virtual worksheet and it explained to me how I did it wrong again... and well rested brain... THEN watching this video again... and I'm like.... OHHHHHH lol I made it more complicated then it should be of been. Thank you for making these videos!!! Without them I would be so lost in class. But now! I have a 96% average

Thanks for the very clear explanation. I am a semi-retired music teacher, and I am trying to learn/relearn math I haven't had in many decades. Your videos are very well-done, and very helpful.

Thank you making this video. It made me understand point slope form a lot better.

Gee thanks man! I have a test and I missed this lesson so yay

Way better than my teachers can explain it. Thanks a lot for a clear explanation!!

You my friend, have a talent for teaching. thanks!

No questions at all thank you!! I'm gonna surprised my teacher! Spring trap time!

Your videos are very helpful! I honestly don't know why there are so many hate comments on the software. You're explaining everything perfectly and there are people complaining about COLORS. It's not very distracting at all, it just helps separate everything in order. I used to look at Kahn Academy and not like it at all, if im going to be honest. I think it might have just been my annoyance to get the math over with that I didn't actually concentrate on what the videos were actually saying. The only reason you don't understand is because you're rushing or you're not willing to learn (personal experience) But what im trying to say is that your videos helped me so much over the years. Thank you.

thank you this was really helpful

This literally helped me so much u r the best!

Thanks for teaching me how to do my work.

You really helped me out with a lot in my Math 1 class. Thank you so much.

Thank you so much for this, I have to take the state standardized test tmr and this is the only thing I don’t remember

Very nicely explained...AWESOME

Finally something useful

My teacher's formula(idk if thats what u call it) for the point slope form is y-y¹=m(x-x¹) but its just the same for how you solve it

My school teaches this a little different. Instead of using a and b for points we use y1 and x1, only the 1s are tiny little 1s by the letter but I don't how to type those. For the slope formula we use y2-y1 over x2-x1. For homework, some of the questions give us two sets of points, for example (5,1) and (3,-7) and we have to use these but it doesn't tell us which set is the ones and which are the twos and I'm not sure how to tell. Can someone help me with this?

My teacher teaching me: Teacher: You failed the test :) Me: You failed to teach me Khan Academy teaching me: Teacher: You passed! Keep asking questions to improve your self! Me: I'll pass, we have a thing called Khan Academy. (Actual story)

It would help if the variable b, in the point-slope formula, y-b=m(x-a) was clarified to infact be the same variable b that is in the slope-intercept formula, y = mx+b. It took me rearranging the formula on my own to figure out that when a, the second point's x value, is zero the formula yeilds y-b=mx, aka the y intercept formula, proving the b is the same. This was very confusing and seemingly ambiguous from the video.

I've learned this like 100 times but I can't ever remember it...my guess is because I never use it

given point and slope, why is it so rare to find the equation: b=y'-x'm (where b is Y intercept). After all, our missing link is.... b , yes!

How did it go ?

so you want to get it to slope intercept form?

But then is 5 (b) your y intercept?

I now understand this but I know I am never going to use this

Why is this not making sense to me? I keep getting the same answer for the problem I'm working but it doesn't satisfy the line. In this example if you were to substitute "x" for 0 then y=19 but that isn't a point on the given line. Yet this seems to be the correct equation for the line. PLEASE HELP

Jayson Grey well here you do not need to find out the values of x and y. U just have to find the equation of a line. Let me give u an example:- suppose I have m=2, y1=3 and x1=4 Then u just have to put the value of them in the equation and u will get 5=2x-y. THAT'S IT! That's the equation of the line. Hope u know the first degree equation ax+by+c=0. Hope this helps!

Instructive but near the end difficult to follow because the captions get in the way of the fractions.

Sal khan your math Jesus because you my math savior

Pov your doing online school 🏫

its y-y1=m(x-x1)

I have a skills test in my math analysis class 😭😞

2x +19 is that a answer ?

Is it confusing to anyone else to have a multiple b s meaning 2 different things in the same example?

What if you arent given slope, just two sets of points

@elijaguy

Slope is defined as rise over run. Two points might be (x,y)(x',y') Rise is y'-y (delta y) Run is x'-x (delta x) Slope will be delta y (rise) divided by delta x (run). [Delta means how much greater is y' than y.]
