Solve the system of equations using the linear combination method. {4x−3y=127x−3y=3 enter your answers in the boxes.

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.
