Writing Inequalities from Number Lines

The video tutorial introduces inequalities, explaining the symbols used to compare unequal values. It covers the representation of inequalities on number lines, focusing on open and closed circles. The tutorial includes examples and practice problems to help students understand how to interpret and solve inequalities using number lines.

What does an open circle on a number line represent?

• A value that is less than the number

• A value that is greater than the number

• A value that is not included in the inequality

• A value that is exactly equal to the number

What does a closed circle on a number line indicate?

• The number is not included in the range

• The number is exactly equal and included in the range

• The range starts after the number

• The range ends before the number
