    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.
