Question

I need help with this right now. Please.

Answer 1

Explanation:

Part D

Do part d first. That gives you a big hint.

The height of a is 2 units. The height of d = 6 units. Therefore the heights are related as h_b / h_a = 3/1

Now go back and do A

Part A

Call the coordinates of B = (x,y)

Call the coordinates of A = (x',y')

So it looks like you are going from A to B

x = 3x'

y = 3y'

Part B

You are going in the opposite direction. You are going from B to A

x' = x/3

y' = y/3

Part C

The scale factor to go from B to A is 1/3

The scale factor to go from A to B is 3
