The video tutorial explains how to solve systems of inequalities by graphing. It covers the use of slope-intercept form to graph inequalities, the importance of testing points to determine the solution region, and how to identify the feasible region where the solutions to both inequalities overlap. The tutorial emphasizes the need to flip the inequality sign when dividing by a negative number and provides step-by-step instructions for graphing each inequality and shading the feasible region.
