Graphing and Analyzing Inequalities

The video tutorial covers the basics of graphing linear inequalities, including the use of symbols like less than and greater than, and how to interpret them on a graph. It explains the importance of boundary lines, shading, and solution sets, and provides examples of graphing systems of inequalities. The tutorial also discusses how vertical and horizontal lines affect shading and solution sets. Finally, it highlights real-world applications of graphing inequalities in fields like business and engineering.

What symbols are commonly used to represent inequalities?

• Equal to and not equal to

• Parallel and perpendicular

• Less than and greater than

• Approximately equal to and not approximately equal to
