1 Answer

  1. To rotate a point 90° clockwise about the origin, you switch the coordinates and change the sign of the new y-coordinate.

    For point B (2, 4):
    1. Switch the coordinates: (4, 2)
    2. Change the sign of the new y-coordinate: (4, -2)

    So, the new coordinates of point B after a 90° clockwise rotation are (4, -2).
