For 9-10, use the graph below. 9. What is the length of AB? Explain your reasoning.

10. What is the midpoint of CD? Justify your answer.

Step-by-step explanation:

A = (5,-5)

B = (-1,-5)

AB = (5 - - 1) + (-5 - - 5)

AB = 6

Mid Point CD

C = - 3,4

D = 6,3

Midpoint = (-3 + 6)/2 , (4+3)/2

Midpoint = 3/2, 7/2

Midpoint = 1.5, 3.5

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
