To find the coordinates of point D' after a 90° counterclockwise rotation about the origin, you can apply the following transformation to the coordinates of point D (x, y):
- The formula for a 90° counterclockwise rotation is:
- \( D'(x', y') = (-y, x) \)
If you have the original coordinates of point D, you can substitute them into this formula.
For example:
- If the original point D is (4, -8), applying the transformation gives:
- \( x' = -(-8) = 8 \)
- \( y' = 4 \)
Thus, the new coordinates after the rotation would be (8, 4).
Please specify the original coordinates of point D to provide an accurate answer. If D is indeed (4, -8), then the correct response is (8, 4).

To find the coordinates of point A' after a 270° counterclockwise rotation about the origin, you can use the following transformation:
- The formula for a 270° counterclockwise rotation is equivalent to a 90° clockwise rotation, which can be expressed as:
- \( A'(x', y') = (y, -x) \)
If you have the original coordinates of point A (let's say they are (x, y)), substitute those values into the formula.
For example:
- If the original point A is (x, y):
- \( x' = y \)
- \( y' = -x \)
In order to provide an accurate response, please provide the original coordinates of point A.
However, if we assume the initial coordinates of point A are (1, 2), after a 270° counterclockwise rotation the coordinates would be:
- \( x' = 2 \)
- \( y' = -1 \)
Thus, the new coordinates A' would be (2, -1).
Based on this calculation, if the original coordinates of point A were indeed (1, 2), then the correct response would be (2, -1).
