To reflect a point across the x-axis, we change the sign of the y-coordinate while keeping the x-coordinate the same.
The point given is \((-5, 10)\).
To reflect it across the x-axis:
- The x-coordinate remains \(-5\).
- The y-coordinate changes from \(10\) to \(-10\).
Therefore, the reflected point is \((-5, -10)\).
