Thread: Equation of Perpendicular bisector

Hey everyone Check my work please.

Q. Find the Equation of perpendicular bisector of the line joining (3,1) and (-5,-7)

1) Slope = 1

2) Negative reciprocal = -1

3) Midpoint = (-1,-3)

4) Equation of the line
y=-x-4

All correct?

Hi Gary,
You have all the right answers. Your teacher could say show your work. For example how did you get 4. No answer is necessary since I believe you do know it.
