    the slopes:

    Mjk=1/3

    Mlk=-2

    Mml=2/5

    Mmj=-3/2

    JKLM is not a parallelogram

    because

    neither pair of opposite sides

    is parallel.

    I find it easier to compute slopes from a plot of the points. Simply count the squares. (See the source link.)

    segment ... ∆y/∆x

    JK ... 2/6 = 1/3

    LK ... -6/3 = -2

    ML ... 2/5

    MJ ... -6/4 = -3/2

    JKLM is not a parallelogram because neither pair of opposite sides is parallel.

    slope of JK = (3-1)/(2-(-4))

    you can do the calculation.
