Question

If P = (3,2), find the imageof P under the following rotation.90° counterclockwise about the origin([?], [])Enter the number that belongs inthe green box.

Answer 1

Given the point P(x,y) as the point of the pre-image and if it goes through a rotation of 90 degrees counterclockwise about the origin, the point of the image will be in the form P(-y, x)

The transformation rule for

Using the above principle of transformation on the point P(3,2) as stated above

The image under the rotation of 90 degrees counterclockwise about the origin would be

P(-2,3)
