    REINY answered your earlier post and she said to try doing it yourself.

    She did a similar example for you to follow. I pasted her example below.

    Post your work if you get stuck.

    slope of line through the two points = (6-2)/(3-1) = 2

    so the slope of your new line = -1/2
    since the slopes must be negative reciprocals of each other.

    new equation:
    y = (-1/2)x + b
    but (2,2) lies on this
    2 = (-1/2)(2) + b
    3 = b

    y = (-1/2)x + 3
