(a food ball team has four chances with the ball keep going to try to make a touchdown. a team gained 7 yards, lost 2, gained 4,and lost 1(. how many total yards the teams move forward and backwards

Gained in total = 10.

Moved Backwards in total = 3.

But if you keep them all together with the amount taken away, they've only gained 8 yards.

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
