Learn how to graph a system of three linear inequalities

The video tutorial covers graphing systems of linear inequalities, focusing on converting inequalities to equations, graphing in slope-intercept form, and understanding the significance of dashed and solid lines. It explains how to determine shading regions using test points and solve literal equations to find Y. The tutorial also covers graphing horizontal lines and identifying the feasible region where all inequalities are true.
