Step-by-step explanation:
Answer: A. -2/5
Step-by-step explanation:
slope of line B is 5/2
Perpendicular lines have slopes that are the opposite of the reciprocal of each other
so the opposite reciprocal would be -2/5
The height of ABC = 2 units.
The height of A'B'C' = 6 units.
Dilation = 6/2 = 3
You multiply 3 and 2. you get 6-y=9. then you subtract 6. you get -y=3. you cant have negative y so you multiply -y and 3 by -1. you get y=-3,that is your answer.
