Graphing Linear Inequalities on a Number Line

The video tutorial by Mr. Whit from Fort Ben Tutoring covers solving and graphing inequalities on a number line. It explains the use of different inequality symbols, how to represent solutions using open and closed circles, and the use of parentheses and brackets. The tutorial also covers interval and set builder notation, and solving compound inequalities. The video concludes with a request for feedback and subscription.

Which symbol represents 'less than' in inequalities?

• ≤

• >

• <

• ≥

How do you represent a value that is not included in the solution on a number line?

• Closed circle

• Bracket

• Open circle

• Square

What is the interval notation for the solution x < 5?

• (5, ∞)

• (-∞, 5]

• [5, ∞)

• (-∞, 5)

How do you represent a value that is included in the solution on a number line?

What happens to the inequality symbol when you divide both sides by a negative number?

• It becomes an equal sign

• It stays the same

• It disappears

• It reverses direction

How do you represent the solution x > 9 and x ≤ 13 on a number line?

• Open circle at 9 and closed circle at 13
