Which equation describes the line with a slope of -3 and passes through the point (-4,0) and how do you know? a) y+3 = -4(x-7) b) y-7 = -3(x+4) c) y-7 = -4(x+3) d) y+4 = -3(x-7)

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.
