Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does an open circle on a number line represent?

Back

An open circle indicates that the number is not included in the solution set (e.g., x > -2).

Front

What does a closed circle on a number line represent?

Back

A closed circle indicates that the number is included in the solution set (e.g., x ≥ -5).

Front

How do you graph the inequality x > -2?

Back

Draw an open circle on -2 and shade to the right.

Front

How do you graph the inequality x ≥ 2?

Back

Draw a closed circle on 2 and shade to the right.

Front

When graphing b < 6, would you use an open or closed circle?

Back

Open circle.

Front

What is the correct inequality for a graph with an open circle on 2 and shading to the right?

Back
