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.
