To perform a 90-degree counterclockwise rotation about the origin, you can use the transformation rule for the coordinates \((x, y)\), which becomes \((-y, x)\).
For point D, with coordinates (-4, -8):
- Identify the coordinates: \(x = -4\) and \(y = -8\).
- Apply the transformation:
- New x-coordinate: \(-y = -(-8) = 8\)
- New y-coordinate: \(x = -4\)
Thus, the coordinates of point D' after the rotation will be:
D' = (8, -4)
