Step-by-step explanation:

The rule for this dilation is:

  • (x, y) → (2x, 2y)

Apply this rule to the given points to work out the points of the image:

  • 1. A(4, 6) → A'(8, 12)
  • 2. B(-2, 2) → B'(-4, 4)
  • 3. C(5, -3) → C'(10, -6)

4. Point A(2, 7) → B(18, 63)

The scale factor is:

  • 18/2 = 63/7 = 9
