  1. (5-7)/(0-(-3)) = -2/3
    (3-5)/(3-0) = -2/3 remarkable
    (1-3)/(6-3) = -2/3

    just for sport
    (1-7)/(6-(-3)) = -6/9 = -2/3 how do you like that? It might be a straight line through those points with slope = -2/3
    Try one of those points in
    y = -(2/3)x + b
    7 = (-2/3)(-3) + b
    7 = 2+b
    b = 5
    so
    y = -(2/3) x + 5 goes through all points I believe
    Try it in the last point
    1 = -(2/3)(6) + 5 ?
    1 = -4 + 5
    1 = 1 , sure enough, done
