Question

Answer 2

The correct option is;

90 degrees counterclockwise rotation

Explanation:

The coordinates of the preimage before rotation = K(17, -12)

The coordinate of the image of the preimage after rotation = K'(12, 17)

Therefore, the rotation transformation, transforms, the preimage (x, y) to the image (-y, x), which is equivalent to a rotation of 90 degrees counterclockwise
