Learn how to determine the feasible region of three linear inequalities ex 16

The video tutorial explains how to graph a system of linear inequalities by treating them as equations initially, then determining the shading and feasible region. It covers using both standard and slope-intercept forms for graphing and emphasizes the importance of dashed boundary lines for inequalities that are not inclusive. The tutorial concludes with determining the feasible region by using test points to verify which side of the boundary lines to shade.

What is the process for determining the feasible region after graphing the inequalities?

How do you use a test point to determine the shading direction for the inequalities?

What does it mean if a test point satisfies all inequalities in the system?
