11-21.

Multiple Choice: Assume that the coordinates of $ΔABC$ are $A(5, 1)$, $B(3, 7)$, and $C(2, 2)$. If $ΔABC$ is rotated $90º$ clockwise ($\circlearrowright$) about the origin, the coordinates of the image of $B$ would be:

1. $(−3, 7)$

1. $(−7, 3)$

1. $(7, −3)$

1. $(7, 3)$

Use the eTool below to help determine the coordinates.
