    A = Midpoint of PQ

    Ax = (-6 + -2) / 2 = -4

    Ay = (2 + 8) / 2 = 5

    A = (-4, 5)

    ----------------------

    B = Midpoint of PR

    Bx = (-6 + 4) / 2 = -1

    By = (2 + -4) / 2 = -1

    B = (-1, -1)

    -----------------------

    m = Slope AB

    m = rise/run

    m = (y₂ - y₁) / (x₂ - x₁) 

    m = (-1 - 5) / (-1 - -4)

    m = -6/3

    m = -2 <––––––
