This is from “solving using the quadratic formula (Real world applications)” by the way Remember to set everything= 0 before using the quadratic formula!
x^2 + 4x + 17 = 8 - 2x

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.
