Use the image to answer the question.

A horizontal line separates 2 triangles. The triangle above the line is made up of points upper X, upper Y, and upper Z, while the triangle below the line is made up of points upper X prime, upper Y prime, and upper Z prime.

Triangle XYZ

To find the coordinates of vertex \( X' \) after reflecting point \( X \) over a horizontal line of reflection, we follow these steps:

  1. Identify the original coordinates of point \( X \).
  2. Determine the equation of the horizontal line over which the reflection occurs.
  3. 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.
