The Graphing Method:
- Graph each equation of the system
- Write the equation in slope-intercept form
- $$y = mx + b$$
- Use the y-intercept as a point (0, b)
- Use the slope (rise/run) to get an additional point
- Locate the point of intersection
- Since this point lies on both lines, it is the solution for the system
- Check the solution
