Point A(4,−7) is reflected in the x-axis. Identify the coordinates of its image after this reflection.(1 point) The coordinates of A′ are (,).

1 answer

When a point is reflected in the x-axis, the x-coordinate remains the same while the y-coordinate changes sign.

For point A(4, -7):

  • The x-coordinate remains 4.
  • The y-coordinate changes from -7 to 7.

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

So, A′ are (4, 7).
