Please please help, i need to get a good grade on this to pass geometry A parallelogram that is not a rectangle is graphed in a coordinate plane. The endpoints of a diagonal of the parallelogram are (1, -3) and (9,2).

What could be the coordinates of the endpoints of the other diagonal?

Explain your reasoning. Be sure to include any geometric theorems you used in your reasoning.

associative property hopes this ! : )

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

5x+10 is the correct one
