D
D' = ([?], [])

Answer 1

(6, -6)

Explanation:

The question does not state around which point the dilation takes place. We will assume that the dilation with a scale factor of 3 occurs around the origin.

Pre-image coordinates for image D are (2, -2)

With a scale factor of 3, the dilated coordinates any point (x, y) dilated around the origin are (3x, 3y)

Hence coordinates of D' are (3 · 2, 3 · (-2)) = (6, -6)
