L(-1,3)

after a reflection over the

y

-axis.

Submit

Reflect over y-axis: To reflect a point over the y-axis, change the sign of the $x$ -coordinate while keeping the $y$ -coordinate the same.
X-coordinate change: The $x$ -coordinate of point $L$ is $-1$ . After reflection over the $y$ -axis, it becomes $1$ .
Y-coordinate remains: The $y$ -coordinate of point $L$ is $3$ . After reflection over the $y$ -axis, it remains $3$ .
Final image: The image of point $L$ after reflection over the $y$ -axis is $(1,3)$ .
