Graphing Inequalities on a Number Line

The video tutorial discusses the importance of water intake and defines a variable W to represent the number of ounces of water consumed daily. It explains the concept of inequalities using W, focusing on drinking more than 64 ounces and the difference between strictly greater than and greater than or equal to 64 ounces. The tutorial uses a number line to visually depict these inequalities.

Why is 64 not included in the inequality W > 64?

• Because 64 is not a number

• Because 64 is less than 64

• Because 64 is equal to 64

• Because 64 is greater than 64
