How to solve a system of equations by graphing

The video tutorial explains how to solve a system of equations by graphing. It covers two main methods: using the slope-intercept form and finding the X and Y intercepts. The instructor demonstrates how to convert equations into the slope-intercept form and graph them, as well as how to find intercepts and connect them to form a graph. The tutorial includes a sketching exercise to approximate solutions and highlights the importance of using graph paper for accuracy. The video concludes with a summary of the methods and a rough estimation of the intersection point.
