Question

what is the image of the point (9, -7) after a rotation of 270° counterclockwise about the origin? answer attempt 1 out of 2

Explanation:

Step1: Recall rotation rule

The rule for a $270^{\circ}$ counter - clockwise rotation about the origin is $(x,y)\to(y, - x)$.

Step2: Apply the rule

Given the point $(9,-7)$, substituting $x = 9$ and $y=-7$ into the rule. We get $(-7,-9)$.
