A basketball player bounces the ball 30 times per minute. He chews his gum 20 times per minute. If both just happened how many times will they happen together in the next 4 minutes?

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.
