Solve a System of Equations by Graphing by Maria Kovoros and Megan Ruiz


 * Summary:**

A System of Equations is a set of two or more equations with the same variables (x and y) graphed on the same coordinate plane.
In order to solve a system of equations by graphing, the answer that you are looking for is an ordered pair (x,y) that makes ** BOTH EQUATIONS ** true. To solve a system by graphing you must:
 * 1) Solve for y.
 * 2) Graph both equations on the coordinate plane.
 * 3) Look for the ** POINT OF INTERSECTION ** - this point (x,y) is the point that makes both equations true.

It is also possible to check your answer by:
 * 1) Plugging ** BOTH ** of the answers you got, for x and y, into the original equations making sure ** BOTH ** of the solutions work.

 * Summary:** To solve a system of equations graphically, graph both equations and see where they intersect, with a set of two or more equations with the same variables. The intersection point is the solution. You write the solution in ordered pairs.
