To prove that parallelogram
JKLM is a rectangle, given
the coordinates of its
vertices, Ali decided to
show that both pairs of
opposite sides are
congruent. To do so, which
calculation must Ali
perform?

Find the slope of all
4 sides.

Find the midpoint of all of 4 side.

Find the length of all Find the length
all 4 sides.

find the length of 2 side

35 is an outlier

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
