How to determine if these two function are linear or not
1. 2x+y=4
2.2+y=3
x 4 2

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.
