Question

Let P(-6,4) be a point on a rectangle PQRS. What are the coordinates of P if the rectangle is dilated by a scale factor of 3/8?

Answer 1

(-2.25, 1.5)

Explanation:

If dilation is about the origin, each of the coordinates is multiplied by the dilation factor:

P' = (3/8)P = 3/8(-6, 4) = (-18/8, 12/8)

P' = (-2.25, 1.5)
