# Solving Linear Simultaneous Equations: Graphically

### What is a linear simultaneous equation?

Two lines will always intersect unless they are parallel. The way to find the point of intersection on a graph involves you solving the two equations and can involve two methods, graphically or algebraically. The following videos will explain the graphical method. By drawing both equations onto a graph or alternatively using a table of values, allows for you to find the point of intersection for the two equations. This lesson will show you how to solve linear simultaneous equations graphically in HSC Standard Math.
