What is the negative 90 degree rotation of 3 and 5?

To find the negative 90-degree rotation of the point (3, 5), you can use the rotation formula for a point (x, y) around the origin. The formula for a negative 90-degree rotation is (y, -x). Applying this to (3, 5) gives you (5, -3). Thus, the negative 90-degree rotation of the point (3, 5) is (5, -3).
