3.3 homework - reflections and translations - 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 the rule

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

Answer:

$(0,-10)$
