Graphing Inequalities on a Number Line

In this video, Mr. J explains how to graph the inequality X < 0 on a number line. He starts by placing an open circle at zero to indicate that zero is not included in the solution set. He then shows that the solution includes all numbers less than zero, represented by an arrow pointing to the left. The video concludes with a brief summary and an invitation to explore more detailed explanations and examples.

What does the inequality X < 0 mean in terms of number line representation?

• X is not a number

• X is less than zero

• X is equal to zero

• X is greater than zero
