A horizontal translation of a figure in the coordinate plane affects which coordinate?

Explanation:
Moving a figure horizontally means sliding it left or right along the plane, so every point on the figure shifts along the x-axis. This changes the x-coordinate by the amount of the shift, while the y-coordinate stays the same because there is no up-or-down movement. For example, moving a point from (4, -2) three units to the right yields (7, -2). A vertical shift would change the y-coordinate instead, leaving x unchanged.
