Learn how to graph and shade a linear inequality that is horizontal

The video tutorial explains how to graph linear inequalities, focusing on identifying line types, solving for Y, and graphing equations with one variable. It covers horizontal lines and testing points to verify solutions, emphasizing the difference between solid and dashed lines in inequalities.

What is the significance of the type of line when graphing a linear inequality?

How do you determine whether to use a solid or dashed line when graphing an inequality?

Explain the process of solving for Y in slope-intercept form when graphing a linear inequality.

What does it mean when the inequality is represented as Y is greater than or equal to 2?

How can you test whether points are above or below the line in a linear inequality?
