Harry and terry are each told to calculate 8−(2+5)8−(2+5). harry gets the correct answer. terry ignores the parentheses and calculates 8−2+58−2+5. if harry's answer is hh and terry's answer is tt, what is h−th−t?

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.
