Question

ab is rotated 270° counterclockwise about the origin to produce ab. write the rule for the rotation. (x, y) → (□,□)

Explanation:

Step1: Recall rotation rules

A 270 - degree counter - clockwise rotation about the origin has a specific rule for transforming coordinates.

Step2: Apply the rule

The rule for a 270 - degree counter - clockwise rotation about the origin for a point $(x,y)$ is $(x,y)\to(y, - x)$.

Answer:

$(y, - x)$
