Answer 1

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)**
