Jason loves to play the piano but doesn't like practicing the exercises his piano teacher assigns. Jason knows the exercises will help him play better though, so he tries to motivate himself using his favorite treat — chocolate chip cookies. Jason gives himself 5 cookies for every hour he practices.
There is a proportional relationship between the amount of time (in hours) that Jason practices the piano, x, and how many cookies he gives himself, y.
Graph this relationship. Select two points to draw a line.
What is the slope of the line?

3) Yes. They have a common factor of 2x. So, it could be combined as 2x(4 - 1).
4). Yes. They have a common factor of 5. So, it could be combined as 5(3 + 2).
5). Yes. They have a common factor of t². So, it could be combined as t²(7 + 9t³).
6. Yes. They have a common factor of 3. So, it could be combined as 3(y³ + x⁶).
