Solving a linear system of two equations by graphing

The video tutorial explains how to graph a linear system of equations by plotting two equations, y = 5x + 2 and y = 3x, on a graph. It demonstrates how to identify the y-intercept and slope for each equation, plot the lines, and find their intersection point, which is the solution to the system. The tutorial concludes by explaining that the solution is consistent and independent, as there is only one intersection point.
