The video tutorial explains how to use linear programming to find the minimum value of an objective function subject to constraints. It covers graphing inequalities, finding intercepts, and determining the feasible region. The tutorial also demonstrates how to calculate the minimum value of the objective function using the vertices of the feasible region.

What is the primary goal of using linear programming in this context?

• To find the minimum value of the objective function

• To graph all possible solutions

• To eliminate all constraints

• To find the maximum value of the objective function
