To find the coordinates of the points A', B', and C' after a dilation with a scale factor of 3 centered at the origin, we multiply each coordinate of the original points by the scale factor.

  1. Point A (-2, -2):

    • A' = (scale factor) × (original coordinates)
    • A' = 3 × (-2, -2) = (-6, -6)
  2. Point B (-4, -3):

    • B' = (scale factor) × (original coordinates)
    • B' = 3 × (-4, -3) = (-12, -9)
  3. Point C (-2, -5):

    • C' = (scale factor) × (original coordinates)
    • C' = 3 × (-2, -5) = (-6, -15)

Thus, the coordinates after dilation are:

  • A' = (-6, -6)
  • B' = (-12, -9)
  • C' = (-6, -15)

So, the final answers are:

  • A' = (-6, -6)
  • B' = (-12, -9)
  • C' = (-6, -15)
