Not all systems have a single solution. To begin the video, the narrator reviews the different number of solutions possible with a system of linear equations. He continues with examples of solving systems of equations by graphing. Unlike the previously worked examples, the solutions for the examples have no or infinitely many solutions.

Instructional Ideas
- Have the class put in their own words when a system has one solution, no solution, or infinitely many solutions
Classroom Considerations
- Individuals should be comfortable changing equations into slope-intercept form
- Class members must know how to graph linear equations
- This video is hosted on YouTube
Pros
- Identifies the slope and y-intercept for each equation
- Uses colors to distinguish between the two equations and graphs
Cons
- None
