Question

A dilation centered at the origin maps equation onto equation with A(4, -8), B(10, 6), A'(2, -4) and B'(5, 3). What is the scale factor of the dilation?

Answer 1

Any ideas?

Answer 2

A. 2/1
B. 1/1
C. 1/4
D. 1/2

Answer 3

What do you need to do to go from A(4, -8), B(10, 6) to A'(2, -4) and B'(5, 3)?

Answer 4

@skullpatrol what do you mean ?

Answer 5

$$\Huge A(4, -8), B(10, 6)$$ $$\huge A'(2, -4) B'(5, 3)$$

Answer 6

i have no idea what to do i'm taking honors geometry

Answer 7

Look closely at the values at the top and compare each x-coordinate.
