Tanya's rotation maps point K(24, –15) to K'(–15, –24). Which describes the rotation? 90 degrees clockwise rotation 270 degrees clockwise rotation 180 degrees rotation 90 degrees counterclockwise rotation

A. 90 degrees clockwise rotation

Step-by-step explanation:

Of we have a coordinate axis (x,y), if this axis is rotated 90° clock wide, the resulting coordinate of the pre-image will be the coordinate (y -x). Note that the coordinates was swapped and then the new y coordinate negated.

Given the coordinate K(24, -15). If we rotate this clockwisely, first we swap the coordinate axis to have (-15, 24)

Them we will negate the new y coordinate axis to have;

K'(-15, -24)

Therefore the correct answer is 90° clockwise rotation.
