Question

Imagine a counterclockwise rotation of 270 about the origin to the figure choose the coordinates of A

Answer 1

To perform a counterclockwise rotation of 270 degrees about the origin in a coordinate plane, you can use the following transformation formula:

If you have a point \( A(x, y) \), the coordinates of the point after a counterclockwise rotation of 270 degrees will be given by:

\[
A'(x', y') = (y, -x)
\]

This means that for a point \( A(x, y) \):
- The new x-coordinate \( x' \) becomes \( y \)
- The new y-coordinate \( y' \) becomes \( -x \)

If you provide specific coordinates for point \( A \), I can help you calculate the new coordinates after the 270-degree rotation.
