Question

The graph shows an image of a dilation about the origin with a scale factor of One-half.

On a coordinate plane, point A prime is (negative 4, negative 6) and points B prime is (4, 8).

What are the coordinates of the pre-image of A prime, point A?
(–8, –12)
(–12, –8)
(–2, –3)
(–3, –2)

Answer 1

A' = (1/2)·A, so A = 2·A' = 2·(−4, −6) = (−8, −12). Answer: (−8, −12).
