Verified archiveIf you change the sign of a point’s y-coordinate, the correct answer is: The point will cross over the X-axis.
Explanation: When you change the sign of the y-coordinate, you effectively reflect the point across the X-axis. For example, if you have a point (x, y) and you change it to (x, -y), its y-coordinate has switched from positive to negative or vice versa, which means it moves from above the X-axis to below it or the other way around. This results in the point crossing the X-axis.
