Question

I

f point A is located at (–15, –7) and JKL has vertices at J(–22.5, –10.5), K(19.5, –3.0), and L(–4.5, 15.0), find the scale factor ABC to JKL of the dilation from

Answer 1

1.5

Explanation:

The coordinate values of point J are 1.5 times those of point A, so if dilation is about the origin, the scale factor is 1.5.

If the dilation is about some other point, this problem statement does not contain enough information to tell what the scale factor might be.
