perpendicular to line -2x+y=7 contains the point (-4,-2) the equation of line is

  • math urgent urgent urgent -

    -2x+y=7 can be written as
    y=2x+7, so we see it has slope=2

    so, the perpendicular has slope -1/2
    now you have a point and a slope:

    y+2 = -1/2 (x+4)
    and you can massage that as you will.
