Question

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

Explanation:

Step1: Recall rotation rule

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

Step2: Apply the rule

Given the point $(-1,2)$, substituting $x=-1$ and $y = 2$ into the rule $(y,-x)$, we get $(2,1)$.

Answer:

$(2,1)$
