Answer: A - The coordinates of the original point were (-14, -73).

Solution

Assume the original point is (a, b):

1. When the point is reflected over line y = x, the point coordinates become (b, a).

2. When reflected over the x-axis, the coordinates then become (b, -a).

3. When reflected over the y-axis, the coordinates then become (-b, -a)

If the final point is (73, 14), the original point was (-14, -73)
