Two equations are shown: equation 1: 3/4(x - 12) = 12. equation 2: 3/4y - 12 = 12. the value of x is: the value of y is:

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

you need to show us the graph.
