Question

Which of the following is the image of A after a rotation of -90° about the origin?

(0, -2)
(0, 2)
(-2, 0)

Answer 1

Option A. (0, -2)

Explanation:

In the given graph coordinates of point A are (2, 0).

Now this point is rotated by -90° about the origin, that means rotation has been done clockwise by 90°.

Now after rotation this point A will lie on the negative side of the y-axis and the new coordinates become (0, -2).

Therefore, option A. (0, -2) is the correct option.

Answer 2

A would be located at (0,-2)
