To perform a 90° counterclockwise rotation about the origin, you can use the following transformation on the coordinates (x, y):

\[ (x, y) \rightarrow (-y, x) \]

For the point D (-4, -8):

  1. Identify the coordinates: \(x = -4\) and \(y = -8\).
  2. Apply the transformation:

\[ D' = (-(-8), -4) = (8, -4) \]

Thus, the coordinates of D' after a 90° counterclockwise rotation are (8, -4).

Therefore, the correct response is:

(8, -4)
