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

[Abigail]

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?

[joshuahauser]

THANK YOU SO MUCH OMG! I was so confused in class and this video and your one on how to do it on the TI 84 helped a TON!

[prithvilall]
