Find the area of the figures. Tried so many times but the answer I'm getting is 20.5 when it's not the correct answer. It would be nice if someone could help me. Thank you.

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.
