CPM Homework Help : CCG Problem 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:

$\left(-3,7\right)$

$\left(-7,3\right)$

$\left(7,-3\right)$

$\left(7,3\right)$

Use the eTool below to help determine the coordinates.
