Write the equation of the perpendicular bisector of line BC. Point B is located at (–3, 1), and point C is located at (1, 5).
A. y = -1x-4
B. y = -1x+2
C. y = -1x+6
D. y = 1x-4

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.
