CAN SOMEONE HELP WITH #21 FOR BRAINLIEST ASAP

x = 2

y = 1

Step-by-step explanation:

The step 1 was correct but the second step was incrrect, you had to use those values of y = -2x+5 in the second equation : 3x - 2y =4

where 3x - 2(-2x+5) = 4

3x + 4x -10 = 4

x=2

find y :

y = -2(2) + 5

y=1

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
