Question

The graph below shows triangle L’M’N’ , after a 90 counterclockwise rotation about the origin. What were the coordinates of pre-image point L ? A. (-8,5) B. (-5,8) C. (5,-8) D. (8,-5)

Answer 1

First we have to identify the coordinates of L' which are ( -8,-5) then we are rotate our point 90 degrees clockwise. Doing that we obtain the original coordinates. (-5,8). So, the answer would be B.
