Question

question what is the image of the point (-8, 7) after a rotation of 90° counterclockwise about the origin? answer attempt 1 out of 2 score: 2/3 penalty: none show examples

Explanation:

Step1: Recall rotation rule

For a 90 - degree counter - clockwise rotation about the origin, the transformation rule for a point $(x,y)$ is $(x,y)\to(-y,x)$.

Step2: Apply the rule

Given the point $(-8,7)$, where $x=-8$ and $y = 7$. After applying the rule, we get $(-7,-8)$.

Answer:

$(-7,-8)$
