How Do You Figure Out Whether a Boundary is a Part of the Graph of an Inequality?

Note:

Is the boundary part of the graph of an inequality? Here's a hint: the sign of the inequality holds the answer! Learn how to test and see if the boundary is part of the graph of an inequality by watching this tutorial.
