- Step 1: Multiply each coordinate by the scale factor: and .
Answer
(6, 15).
Why not the others: (5, 8): This adds the scale factor to each coordinate. (6, 5): This multiplies only the -coordinate. (2/3, 5/3): This divides by the scale factor, which would be an enlargement of scale factor one third.
