GENERALIZE how to find a constant rate of change between two points:

1) A function with a constant rate of change has a graph that passes through the points

(-2, 4) and (6, 6). Find the rate of change.

2) A function with a constant rate of change has a graph that passes through the points

(6, -1) and (4, 3). Find the rate of change

3) A function with a constant rate of change has a graph that passes through the points

(1, -3) and (4, 6).

a) Find the rate of change

b) Define a function with the constant rate of change found above that passes through the given points

4) Define a function with a constant rate of change whose graph passes through the points (-5, 8) and ( -1, -2)

5) Say hi to Kim and Allison! Okay, let's say that Kim's in the race and 5 minutes past the checkpoint she has ridden 3 miles. 7.5 minutes past the checkpoint she has ridden 6 miles. Assuming she rides at a constant rate, define a function that models this situatiaon.
