To perform a dilation with a scale factor of 5 centered at the origin, we multiply the coordinates of each point by the scale factor.

For point A(1, 2):

  • A' = (1 * 5, 2 * 5) = (5, 10)

For point B(−2, −1):

  • B' = (−2 * 5, −1 * 5) = (−10, −5)

So, the coordinates after dilation are:

  • A' = (5, 10)
  • B' = (−10, −5)

The correct response is: A′ (5, 10) and B′ (−10, −5).
