    (-4,1) is correct. Reflection of an object about the x- and y-axes is equivalent to a rotation of 180 degrees. In addition, rotation of 180 degrees is it's own inverse (just like reflections), so the point has basically done a rotation of 180 degrees, and then had an inverse of 180 degrees, and come back to the original position.
