    Answer:   Slope = -3/7

    ===================================================

    Apply the slope formula

    m = (y2-y1)/(x2-x1)

    m = (6-3)/(-9-(-2))

    m = (6-3)/(-9+2)

    m = 3/(-7)

    m = -3/7

    This means each time you go down 3 units, you go to the right 7 units.

    Slope = rise/run = -3/7

    rise = -3 and run = 7
