Answer:
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
