Question

3.3 classwork - reflections - graded
state the image of the point (10, 0) after a reflection in the line y = -x.

Explanation:

Step1: Recall reflection rule

The rule for reflecting a point $(x,y)$ over the line $y = -x$ is $(x,y)\to(-y,-x)$.

Step2: Apply rule to point

For the point $(10,0)$, substitute $x = 10$ and $y = 0$ into the rule. We get $(-0,-10)$.

Answer:

$(0, - 10)$
