The set of points (–1, 2), (5, 2), (5, –4), and (–1, –4) identifies the vertices of a quadrilateral.

which is the most specific description of the figure the points form?

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=
