Did I do this right? Or do I need to start over.


Find the slope of the line described.
A line perpendicular to -4x+4y=-2

-4x+4y=-2
4y=4x-2
4y/4=4x-2/4
y=1x-1/2

  • Algebra -

    Yes, but you are not finished
    4 y = 4 x -2
    slope of original line is 4/4 = 1
    NOW we need perpendicular
    slope of perpendicular = -1/slope of original
    so slope we want = -1/1 = -1
