Question

What are the coordinates of the image of vertex P?

Answer 1

P'(-16, 0)

Explanation:

You want the coordinates of the image of P(-4, 0) when the figure is dilated by a factor of 4 about the origin.

Dilation

Dilation about the origin multiplies each coordinate by the dilation factor:

P' = 4P

P' = 4(-4, 0) = (-16, 0)

The coordinate of the image point are (-16, 0).
