# Graphs of Linear Systems

Graphs of linear systems provide a visual representation of the relationships between multiple linear equations. These graphs typically consist of lines on a coordinate plane, where the intersection points signify solutions to the system of equations. Understanding these graphs is fundamental in solving simultaneous equations and interpreting their solutions geometrically. By analyzing the slope and intercept of each line, one can determine the nature of the system—whether it has a unique solution, infinitely many solutions, or no solution at all. Graphical representation offers a straightforward approach to grasp the behavior and properties of linear systems efficiently.
