Find A (5, 5) and B (−9, 1) is reflected over the x-axis.
When a point is reflected over the x-axis, the y-coordinate changes sign while the x-coordinate remains the same.
For point A (5, 5), the x-coordinate remains 5 while the sign of y changes. So the reflected point over the x-axis is (-5, -5).
For point B (-9, 1), the x-coordinate remains -9 while the sign of y changes. So the reflected point over the x-axis is (-9, -1).
