Question

What are the coordinates of the points (2,-3) after a counter clockwise rotation of 90 about the Origin?

Answer 1

Explanation:

(2, -3) is in the 4th quadrant. By the counter clockwise rotation of 90° around the origin, it will be in the 1st quadrant.

Any point in the 1st quadrant has both positive x and y coordinates.

So the answer is (3, 2).
