Question

A triangle has vertices of (0,2), (3,0), (0, -3). If it is dilated with center at the origin, and a scale factor of 2, what will be the coordinates of the image?

(0,4), (6,0), (0, -6).
(0,4), (6,0), (0, -3)
(0,7), (6,3), (0, -3)
(0,1), (3/2,0), (0, -3/2)

Answer 1

Answer: (0,4), (6,0), (0, -6)

Explanation:

Dilating at the origin means we can multiply each of the coordinates by the scale factor. In this case, this means we multiply each of the coordinates by 2.
