Graphing Inequalities on a Number Line

This video tutorial by Mr. J explains how to graph inequalities on a number line. It covers four examples: X ≥ 5, W < 1, Y ≤ 32, and A > -4. Each example demonstrates how to use filled or open circles and arrows to represent solutions visually. The tutorial aims to enhance understanding of inequalities through visual representation.

What is the purpose of graphing inequalities on a number line?

• To solve equations

• To find the exact value of a variable

• To visualize inequalities and their solutions

• To compare two numbers

In the inequality X ≥ 5, what does the filled circle at 5 represent?

• 5 is not a solution

• 5 is greater than X

• 5 is a solution

• 5 is less than X

For the inequality X ≥ 5, which direction does the arrow point?

• Right

• Down

• Left

• Up

In the inequality W < 1, why is there an open circle at 1?

• 1 is not included

• 1 is greater than W

• 1 is equal to W

• 1 is included

For the inequality W < 1, which direction does the arrow point?

• Left

• Right

• Down

• Up

In the inequality Y ≤ 32, what does the filled circle at 32 indicate?

• 32 is less than Y

• 32 is greater than Y

• 32 is a solution

• 32 is not a solution

For the inequality Y ≤ 32, which direction does the arrow point?

• Right

• Left

• Up

• Down

In the inequality A > -4, why is there an open circle at -4?

• -4 is greater than A

• -4 is included

• -4 is not included

• -4 is equal to A

For the inequality A > -4, which direction does the arrow point?

• Right

• Up

• Down

• Left

What does the arrow represent in the graph of an inequality?

• The exact value of the variable

• The direction of all possible solutions

• The boundary of the solutions

• The midpoint of the solutions
