The triangle shown will be rotated 90° clockwise about the origin. What are the new coordinates of point B?

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).
