Here's the last video for chapter 8, enjoy it while you can! :)

How about one last Khan Academy Video. This is Sal teaching about how to write equations using the Point Slope Form.  Enjoy!



Here's an exercise practicing this concept on Khan Academy.  You will be converting equations in Point-Slope Form to Slope Intercept Form.

Point Slope Form: y-y1 = m (x-x1)  I can't make the little subscript 1.
Slope-Intercept Form: y = mx + b
