In the coordinate plane, Point B is 1 unit directly above Point A. When Points A and B are reflected about a horizontal line, their images are A' and B', respectively. If the coordinates of A' are (r, s), what are the coordinates of B' in terms of r and s?

(r,s-1)
(r,s+1)
(r-1,s)

If Point B is 1 unit directly above Point A. When Points A and B are reflected about a horizontal line, the point B' will be 1 unit directly below Point A', then If the coordinates of A' are (r,s), the coordinates of B' are (r,s-1)

Answer: First option: (r, s-1)
