Graphing Inequalities Practice

Front

What does the inequality x < -4 represent on a number line?

Back

It represents all numbers less than -4, shown with an open circle at -4 and shading to the left.

Front

How do you represent the inequality b ≤ -2 on a graph?

Back

It is represented with a closed circle at -2 and shading to the left.

Front

When graphing the inequality b < 6, what type of circle is used?

Back

An open circle is used to indicate that 6 is not included in the solution.

Front

What does a closed circle indicate in graphing inequalities?

Back

A closed circle indicates that the number is included in the solution set.

Front

What does an open circle indicate in graphing inequalities?

Back

An open circle indicates that the number is not included in the solution set.

Front

How do you determine which graph corresponds to the inequality k < 3?

Back

Look for a graph with an open circle at 3 and shading to the left.

Front

What is the difference between the inequalities b < 6 and b ≤ 6?

Back

b < 6 does not include 6, while b ≤ 6 includes 6.

Front

What does the inequality b ≥ -2 represent on a number line?

Back

It represents all numbers greater than or equal to -2, shown with a closed circle at -2 and shading to the right.

Front

How can you tell if an inequality is graphed correctly?

Back

Check if the circle is open or closed based on the inequality sign and if the shading direction matches the inequality.

Front

What is the significance of the boundary point in an inequality graph?

Back

The boundary point indicates the limit of the solution set, whether it is included or excluded.
