Graph the system of three linear inequalities and determine the feasible region ex 15

The video tutorial explains how to graph a system of linear inequalities, focusing on three specific inequalities. It covers the process of graphing each inequality separately, determining whether boundary lines are part of the solution, and using test points to identify the solution region. The tutorial emphasizes the importance of understanding slope-intercept form and the role of inequality symbols in graphing.
