one lap around a dirt track is 1/3 mile. it takes Bryce 1/9 hour to ride one lap. what is Bryce's unit rate, in miles, around the track?

substitute:

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

-1, -2, -3, -4, -6

step-by-step explanation:
