When a figure is reflected over the x-axis, the y-coordinate of each point is changed to its opposite. A reflection over the x-axis changes the y-coordinate of a point, inverting its vertical position while maintaining the horizontal position.
When a point undergoes a reflection over the x-axis, the y-coordinate changes but the x-coordinate remains the same. If we have a point with coordinates (x, y) before the reflection, after the reflection it will have coordinates (x, -y). This transformation maintains the horizontal position of the point while inverting its vertical position.
When a figure is reflected over the x-axis, the y-coordinate of each point is changed to its opposite. For example, if a point has coordinates (x, y), the reflected point will have coordinates (x, -y). This means that the reflection over the x-axis changes the sign of the y-coordinate.
