Am • an = am + n, where a is a real number and m and n are integers use the product of powers property to simplify the expression –2x3y4x2y3.

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.
