Graphing a linear inequality greater than or equal to

The video tutorial explains how to graph inequalities by first understanding the slope and y-intercept. It guides through plotting the graph, determining if the line should be solid or dotted, and finally shading the correct region to represent the solution set. The tutorial emphasizes the importance of correctly interpreting the slope and using test points to verify the solution.

What does it mean if a line is part of the solution to an inequality?

What is the process to determine where to shade on a graph of an inequality?

How do you test a point to see if it satisfies the inequality?
