Work Step by Step

In order to solve a system of equations by graphing, first graph each of the given equations. Next, look for intersections between the equations, which are solutions to the equations. If the equations are the same line, then there are infinite solutions. If the equations intersect at a point, that point is the solution to the equations. If the lines never intersect, there is no solution. Thus, we find that the solution is: $$ x=-2,\:y=0$$
