Solving Systems of Equations by Graphing

This video tutorial covers solving systems of equations by graphing. It begins with an introduction to the concept of systems of equations, explaining that the solution is where two lines intersect. The tutorial provides a detailed example of solving a system by graphing, emphasizing the importance of identifying the intersection point. It also discusses special cases such as infinitely many solutions and no solutions, using parallel lines as an example. The video concludes with a real-world application involving reading plans, demonstrating how to set up and solve equations graphically.
