Question

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

Explanation:

Step1: Identify coordinates of A

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

Step2: Apply - 90 - degree rotation rule

The rule for a - 90 - degree (clockwise) rotation about the origin is $(x,y)\to(y, - x)$. For point A(-8,2), substituting $x=-8$ and $y = 2$ into the rule, we get $A'=(2,8)$.

Answer:

A'=(2,8)
