The coordinates of a quadrilateral are shown: point J (-4.5, 3)
point K (-1.2, 3)
point L (-1.2, 8.7)
point M (-4.5, 8.7)
Brenda claims that quadrilateral JKLM is a square.

Part A

Show or explain why Brenda is not correct.

Part B

Select new coordinates for point L and point M so that quadrilateral JKLM is a square. Show or explain all of the steps you used to determine the new locations of the two points.

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
