How can graphing methods be used to solve a system of linear equations? •how can multiple representations of a system be graphed?

You can graph multiple equations in one plot by merely superimposing them. You plot the x values against the corresponding y values. Usually, you are given an equation in this form y=f(x), where f(x) is a polynomial containing a variable of x. You assign arbitrary values of x, to get the y values and plot them together as one data point.

The point at which the graphs intersect each other is the solution of the problem.
