A fair spinner has 9 equal sections: 4 red, 3 blue and 2 green. It is spun twice.
What is the probability of getting blue both times?

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
