To reflect a point across the x-axis, you keep the x-coordinate the same and negate the y-coordinate.
The original point is (5, 10).
Reflecting it across the x-axis:
- The x-coordinate remains 5.
- The y-coordinate changes from 10 to -10.
Therefore, the coordinates of the reflected point are (5, -10).
The correct response is: (5, −10)
