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.

How can you identify the correct test point for determining shading in a graph?

Why is it important to flip the inequality sign when dividing by a negative number?

What is the process to rewrite an inequality as an equation for graphing?

What is the feasible region in the context of graphing systems of inequalities?
