A point is reflected first over the line y = x, then over the x-axis, then over the y-axis. The resulting point has the coordinates (73, 14). The coordinates of the original point were which of the following?
Answer: A - The coordinates of the original point were (-14, -73). To find the solution, first 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).
