Question

What is the scale factor of the dilation (with center at the origin) if point U (6, 2) becomes U’ (12, 4)?

Answer 1

2

Explanation:

Dilation is when you increase the shape by a factor. It's multiplication or division of the point's coordinates.

6 -> 12

2 -> 4

To get these changes, you must multiply by 2, so 2 is the scale factor.
