Question

unit 4 transformations > rotations as functions
use rotation mapping to locate c after a - 90 - degree (clockwise) rotation about the origin.
(1 point)

Explanation:

Step1: Recall rotation rule

The rule for a - 90 - degree (clockwise) rotation about the origin is $(x,y)\to(y, - x)$.

Step2: Identify coordinates of point C

From the graph, point C has coordinates $(-5,2)$.

Step3: Apply rotation rule

Using the rule $(x,y)\to(y, - x)$ with $x=-5$ and $y = 2$, we get $( - 5,2)\to(2,5)$.

Answer:

$C'(2,5)$
