Linear inequalities (one variable)

Front

What is a linear inequality?

Back

A linear inequality is a mathematical expression that shows the relationship between two expressions using inequality symbols (like <, >, ≤, or ≥) instead of an equal sign.

Front

What does the symbol '≤' mean in a linear inequality?

Back

The symbol '≤' means 'less than or equal to'. It indicates that the value on the left can be less than or equal to the value on the right.

Front

What does the symbol '≥' mean in a linear inequality?

Back

The symbol '≥' means 'greater than or equal to'. It indicates that the value on the left can be greater than or equal to the value on the right.

Front

When graphing a linear inequality with '≤' or '≥', what type of line is used?

Back

A solid line is used when graphing a linear inequality with '≤' or '≥' to indicate that points on the line are included in the solution.

When graphing a linear inequality with '<' or '>', what type of line is used?

Back

A dashed line is used when graphing a linear inequality with '<' or '>' to indicate that points on the line are not included in the solution.

What does it mean if a solution to a linear inequality is represented on a number line?

Back

It means that all the values in the solution set are included in the shaded region of the number line, indicating which values satisfy the inequality.
