• Solve a linear system of equations graphically.

• Solve a nonlinear system of equations graphically.

• Construct and use a linear system of equations to solve an application problem.

For this lesson, we are focusing on the method of graphing.  The method of graphing is not an algebraic method.

The main steps of the graphing method are:
1.  solve both equation for one variable.
2.  graph both equations on the graphing calculator
3.  use the intersection function on your graphing calculator to find the solutions

The method of graphing can be used with both linear and non-linear equations.  One problem with using the method of graphing is that it is not always easy to solve the equations in terms of one of the variable.
