Solving Systems of Equations by Graphing

Graphing is another way of solving a system of equations. The problem with the graphing method is that if your graph is not exact, and if you are not using graph paper with correct scale you might not be able to correctly read off the answer from the graph. When you graph your two equations, the solution to the system is where the two line intersect. Again with this method, just like all the other methods, after you find your answer you can plug it back in both equations to chech and see if you got the right answer.
