Question

use rotation mapping to locate c after a - 90 - degree (clockwise) rotation about the origin. (1 point) c()

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 $(-4,2)$.

Step3: Apply rotation rule

Substitute $x=-4$ and $y = 2$ into the rule $(x,y)\to(y,-x)$. We get $(2,4)$.

Answer:

$(2,4)$
