reflection over the line y = x of the point (-9,5)
answer
(-9,-5)
(5,9)
(-5,9)
(5,-9)

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ over the line $y = x$, the coordinates are swapped. So the new point is $(y,x)$.

Step2: Apply rule to given point

For the point $(-9,5)$, swapping the $x$ - and $y$ - coordinates gives $(5, - 9)$.

Answer:

$(5, - 9)$
