Which ordered pair (x, y) is a solution to the given systems of linear equations? 3x+3y=-3 and -2x+y=2

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
