Graphing Inequalities on Number Lines

The video tutorial introduces inequalities and demonstrates how to graph them on a number line. It explains the use of open and closed circles to represent whether a number is included in the inequality. The tutorial covers graphing x values that are greater than or equal to 8 and less than or equal to 11, and discusses how to write and interpret these inequalities. The instructor uses engaging language and examples to clarify the concepts.

What are the two important numbers mentioned in the lesson?

Explain the difference between an open circle and a closed circle on a number line.

How would you graph the inequality x is greater than or equal to 8?

What does it mean when we say x is less than or equal to 11?

Describe how to express the inequalities using 'and' or 'or'.
