Graphing a system of two inequalities in slope intercept form

The video tutorial explains how to solve systems of inequalities by graphing. It covers converting inequalities to equations, graphing each inequality separately, and determining the shading regions using test points. The tutorial emphasizes the importance of dashed lines for inequalities that are not inclusive and demonstrates the process of plotting y-intercepts and slopes. Finally, it shows how to identify the solution region where both inequalities are true.

What is the significance of the test point (0,0) in graphing inequalities?
