M(-4,-2) is the midpoint of RS. If S has coordinates (-2,5), find the coordinates of R.

  • Midpoint Help / Math - ,

    Midpoint formula:

    M = [ (x1 + x2)/2 , (y1 + y2)/2]

    (-4,2) = [ (-2 + x)/2 , (5, + y)/2 ]

    -4 = (-2 + x)/2 and 2 = (5 + y)/2
    -8 = -2 + x. and 4 = 5 + y
    -6 = x. and -1 = y

    Coordinates of R (-6, -1)
