  1. 2 y = -x + 8
    y = -(1/2) x + 4
    so slope = -1/2

    -2 = -(1/2) 5 + b
    -2 = -2.5 + b
    b = .5 = 1/2
    so
    y = -(1/2) x + 1/2

    2 y + x = 1

  2. sorry, slope intercept form is
    y = -(1/2) x + 1/2

  3. the new equation will differ from the old equation only in the constant
    so new: x+2y = c , but (5,-2) is on it, so
    5-4 = c = 1

    x + 2y = 1
