Master How to graph vertical and horizontal linear inequalities

The video tutorial explains how to graph linear inequalities involving vertical and horizontal lines. It begins with an introduction to graphing inequalities and then demonstrates graphing the equation Y = -1, followed by graphing the inequality Y < -1 using test points to determine shading. The tutorial continues with graphing Y = 3 and X = 5, explaining the use of test points and shading for each. Finally, it covers graphing X < -2, emphasizing the importance of rewriting inequalities and using test points to verify solutions.

Describe how to graph the equation Y = -1 and what it represents on the graph.

What is the process for shading the area of the graph that satisfies the inequality?

How can you tell if the line should be dashed or solid when graphing an inequality?
