Question

use rotation mapping to locate a after a -90 degree (clockwise) rotation about the origin. (1 point) o a=(-2,-8) a=(2,8) o a=(-2,8)

Explanation:

Step1: Recall rotation rule

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

Step2: Identify coordinates of point A

From the graph, point A has coordinates $(-8,2)$.

Step3: Apply rotation rule

Using the rule $(x,y)\to(y, - x)$ with $x=-8$ and $y = 2$, we get $A'=(2,8)$.

Answer:

$A'=(2,8)$
