Answer: The coordinates of a point in the plane are represented by a pair of values, (x, y), where x is the horizontal position and y is the vertical position.
When a point is reflected across the x-axis, the x-coordinate remains the same, but the sign of the y-coordinate changes. This is because the x-axis acts as a mirror, flipping the point over to the opposite side of the axis.
So, the coordinates of the reflected point would be (x, -y).
In summary, the x-coordinates of a point and its reflection across the x-axis are the same, while the y-coordinates are different (one is positive, and the other is negative).
