Answer:

  • (x, y) → (4x, 4y)

Step-by-step explanation:

Dilation is applied by the rule:

  • (x, y) → (kx, ky), where k is the scale factor

We have

  • (x, y) = (-2, 3) and (kx, ky) = (-8, 12)

Substitute and solve for k

  • -8 = -2k and 12 = 3k  ⇒ k = 4

So the rule is

  • (x, y) → (4x, 4y)
