How long must $542 be invested at a rate of 7% to earn $303.52 in interest? in a easier way

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.
