A graphical solution to a system of equations means that you draw the system of equations graphs and the reading of it, or the - and -values where the graphs intersect. Say you have the system of equations Thus, it should be to find the pair of and -values that solve the both of the equations at the same time. It is in defining the intersection.
You can either draw the features by hand or with a graphing calculator.
Often it is practical to use calculator to make a graphic solution.
