Answer:

A' = (-6, -6)

B' = (-12, -9)

C' = (-6, -15)

Explanation:

Triangle ABC has the following vertices:

  • A (-2, -2)
  • B (-4, -3)
  • C (-2, -5)

The formula for a dilation with a scale factor of r and centerpoint of the origin is:

  • (x', y') = r(x, y)

Given the scale factor is 3, to determine the coordinates of the vertices after dilation, all we need to do is multiply them by 3.

Vertex A

  • x' = 3(-2) = -6
  • y' = 3(-2) = -6

Therefore, A' has coordinates (-6, -6).

Vertex B

  • x' = 3(-4) = -12
  • y' = 3(-3) = -9

Therefore, B' has coordinates (-12, -9).

Vertex C

  • x' = 3(-2) = -6
  • y' = 3(-5) = -15

Therefore, C' has coordinates (-6, -15).

Therefore, the coordinates of the dilated vertices are:

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