Question

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

Explanation:

Step1: Identify original coordinates of A

Assume A is (-8, 2) from graph.

Step2: Apply 90° clockwise rotation rule

For (x,y), rotation gives (y, -x). Thus, (-8,2)→(2, 8).

Answer:

A. (2, 8)
