did i do this correctly?

Answer:
R" has coordinates (-4,6)
Explanation:
The pre-image is the original, while the image is the altered form. The image is notated by a '. When you alter the image ('), you get ".
T is dilated (multiplied) by 5, so it goes from T = (1,-2) to T' = (5, -10)
R = (-2, 3) → (multiply by 5) → R' = (-10, 15) → (multiply by 2/5 or 0.4) → R" = (-4, 6)
