Question

rotation 270° counterclockwise around the origin of the point (-9,5)

Explanation:

Step1: Recall rotation rule

A $270^{\circ}$ counter - clockwise rotation around the origin has the rule $(x,y)\to(y, - x)$.

Step2: Apply the rule

For the point $(-9,5)$, substituting $x=-9$ and $y = 5$ into the rule, we get $(5,9)$.
