Question

Point A(4,−7) is reflected in the x-axis. Identify the coordinates of its image after this reflection.

Answer 1

To reflect a point across the x-axis, you change the sign of the y-coordinate while keeping the x-coordinate the same.

For point A(4, -7):
- The x-coordinate remains 4.
- The y-coordinate changes from -7 to 7.

Therefore, the coordinates of the image after reflection in the x-axis are (4, 7).
