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 is reflected over the x-axis to create triangle X′Y′Z′. What are the coordinates of vertex X′?

To reflect a point over the x-axis, we keep the x-coordinate the same, but change the sign of the y-coordinate.
The coordinate of point X is (-2,-2).
Reflecting it over the x-axis, the y-coordinate becomes positive. Hence, the coordinates of point X' are (-2, 2).
Therefore, the correct answer is (−2, 2).
