To find the coordinates of vertex \( X' \) after reflecting point \( X \) over a horizontal line of reflection, we follow these steps:
- Identify the original coordinates of point \( X \).
- Determine the equation of the horizontal line over which the reflection occurs.
- Use the formula for reflecting a point over a horizontal line.
Without the specific coordinates of point \( X \) or the line of reflection provided, we cannot determine the exact coordinates of \( X' \). However, assuming we have point \( X \) reflected perfectly across a horizontal line, the y-coordinate of the reflected point \( X' \) will be the same distance from that line as \( X \) but on the opposite side.
If we apply this reasoning to the given answers, we need to check if one of the options represents a proper reflection.
Please clarify the coordinates of \( X \) and the line of reflection to help narrow it down to one of the provided responses.
