ABC is dilated about the origin.

What scale factor was used to make the image A'B'C ?

1/2
- 1/2
-2
2

Answer 1

Its going to be 2

Answer 2

a really easy way to find out is to look at the straight line from b to c and this is going to be an easy start because there is no slope. so you look at it and look at the primed image and look at the straight part and you can see that it has 2 more than the pre image
