Question

which of the following is the rule for reflecting a figure over the y - axis?
$(x,y)\to(x, - y)$
$(x,y)\to(-x, - y)$
$(x,y)\to(-x,y)$
$(x,y)\to(x,y)$

Explanation:

Reflecting a point over the y-axis keeps its vertical (y) coordinate the same, while reversing the sign of its horizontal (x) coordinate. This means a point $(x,y)$ maps to $(-x,y)$.

Answer:

$\boldsymbol{(x,y)
ightarrow (-x,y)}$ (the orange option)
