What is the capital of Egypt? ( Cairo )

1 Answer

  1. The correct answer is: A) The x-coordinates remain the same. and D) The y-coordinates change signs.

    When a point (x, y) is reflected across the x-axis, the x-coordinate stays the same, while the y-coordinate changes sign. Therefore, the image point will be (x, -y). This means that the x-coordinates remain unchanged, and the y-coordinates flip to their opposite values.
