When a point is reflected across the x-axis, the x-coordinate remains the same, while the y-coordinate changes its sign.
If we denote the coordinates of point A as (x, y), after reflecting across the x-axis, the new coordinates will be (x, -y).
However, since the original coordinates of point A are not provided in the question, we can't calculate the resulting coordinates directly. If you can provide the original coordinates of point A, I can then determine the resulting coordinates after reflection across the x-axis.
