Question

what is the result of a reflection over the y = x line of a point (x, y)? (x, y) → (y, x) (x, y) → (x, -y) (x, y) → (-x, y) (x, y) → (-y, -x)

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ over the line $y = x$, the $x$ - coordinate and $y$ - coordinate swap places.

Answer:

A. $(x,y)\to(y,x)$
