VikaD [51]

Answer:

  the dilated coordinates are (12, 9), (6, 9), (12, -6), (6, -6)

Step-by-step explanation:

The dilation factor multiplies each coordinate value when the center is the origin.

__

  (8, 6) ⇒ 1.5(8, 6) = (12, 9)

  (4, 6) ⇒ 1.5(4, 6) = (6, 9)

  (8, -4) ⇒ 1.5(8, -4) = (12, -6)

  (4, -4) ⇒ 1.5(4, -4) = (6, -6)
