To reflect a point \( L(x, y) \) over the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same. The reflected point \( L' \) will be \( (-x, y) \).
For example, if the coordinates of point \( L \) are \( (3, 4) \), the reflection \( L' \) over the y-axis would be \( (-3, 4) \).
Please provide the coordinates of point \( L \) so I can help you find the reflection \( L' \) and assist with plotting it.
