Question

1. what is the transformation rule for a 90 - degree counterclockwise rotation around the origin? a. swap the coordinates and negate the new y - coordinate b. change both coordinates to their opposites c. keep the coordinates the same d. swap the coordinates and negate the new x - coordinate

Explanation:

For a 90 - degree counterclockwise rotation around the origin, if we start with a point (x, y), the new point after rotation is (-y, x). This means we swap the coordinates and negate the new y - coordinate.

Answer:

a. Swap the coordinates and negate the new y - coordinate
