Verified archiveIf you change the sign of a point’s y-coordinate, the point will cross over the x-axis.
Explanation: Changing the sign of the y-coordinate means that if the original point is above the x-axis (positive y), it will move to the same distance below the x-axis (negative y), and vice versa. This movement occurs along the y-direction, hence crossing the x-axis.
