Explain the connection between the solution of a system solved by graphing and the solution to the same system solved by substitution answers

When graphing a system by graphing, you will get two lines, and the point where these lines intersect is considered the solution. Solving by substitution gives you the coordinates of this point, without having to graph these lines. Regardless of the method, substituting the solution into the system for x and y will yield two equations that can be verified as true.
