An airplane flying at 15,000 ft descends to land at an airport. During the airplane's final approach it descends from 15,000 ft to 7, 400 ft in 3 min. What rational number represents the average change in elevation each minute during its final approach?​

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

the answer is 13/48
