Here x, y are the unknown variables in both the equations.

Graph the equation x = 2 which is parallel to the y axis.

Graph the equation y = 3 which is parallel to the x axis.

The solution will be the point which is at the intersection of both the graphed lines.

Hence the point of intersection is (2,3).

Here x, y are the unknown variables in both the equations.

Graph the equation x = -1 which is parallel to the y axis.

Graph the equation y = -1 which is parallel to the x axis.

The solution will be the point which is at the intersection of both the graphed lines.

Hence the point of intersection is (-1, -1).
