The image of P(-2,1) after it is rotated 90° is (-1,-2).
Image = (-1, -2) ;
The image of the point P(-2, 1) after a 90° counterclockwise rotation is P'(-1, -2). This is found by applying the rotation transformation rule, which swaps and negates the coordinates. Therefore, the final coordinates become P'(-1, -2).
