Graphing One-Variable Inequalities on Number Lines

What symbol is used to start graphing an inequality that does not include the number itself?

• An open circle

• A dot

• A closed circle

• A square

In which direction do we shade the number line for an inequality greater than a specific number?

• To the left

• To the right

• Both directions

• No shading is needed

What does shading to the right of a number on a number line indicate?

• The number is not included in the solution

• The solution includes numbers less than the indicated number

• The solution includes numbers greater than the indicated number

• The number is the only solution

How do we show that a variable's value can continue indefinitely in a positive direction?

• By using a double circle

• By shading to the left

• By shading to the right with an arrow

• By not shading

What does an open circle on a number line signify?

• The number is included in the solution set

• The number is the only solution

• The number is not included in the solution set

• The solution set is all numbers except the one indicated

For an inequality less than a number, in which direction should the number line be shaded?

• To the left

• To the right

• No shading

• Both directions

When graphing 'X is less than -2', where do we start shading?

• At 0

• At -2 with an open circle

• At 2 with an open circle

• At -2 with a closed circle

How do we indicate that a number is part of the solution set in an inequality?

• Placing a dot above the number

• By shading the entire number line

• Using a closed circle

• Using an open circle

What does a closed circle on a number line represent?

• The number is included in the solution set

• The solution is only that number

• The solution set is empty

• The number is not part of the solution

In the context of inequalities, what does shading on a number line represent?

• The exact value of the solution

• The range of possible solutions

• A mistake in the graph

• The absence of solutions
