To reflect a point in the x-axis, the x-coordinate remains the same while the y-coordinate changes sign.

Given point A(4, -7), after reflecting it in the x-axis, the coordinates will change as follows:

  • x-coordinate: 4 (remains the same)
  • y-coordinate: -7 changes to 7 (sign changes)

So, the coordinates of the reflected point A' are (4, 7).

Thus, \( A' \) = (4, 7).
