What is a linear inequality?

Back

A linear inequality is a mathematical statement that compares a linear expression to a value using inequality symbols such as <, >, ≤, or ≥.

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

Back

The symbol '>' means that the value on the left is greater than the value on the right.

Front

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

Back

The symbol '<' means that the value on the left is less than the value on the right.

Front

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

Back

The symbol '≥' means that the value on the left is greater than or equal to the value on the right.

Front

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

Back

The symbol '≤' means that the value on the left is less than or equal to the value on the right.

How do you graph a linear inequality with a '>' or '<' sign?

Back

You use a dashed line to indicate that points on the line are not included in the solution.

Front

How do you graph a linear inequality with a '≥' or '≤' sign?

Back

You use a solid line to indicate that points on the line are included in the solution.

Front

What is the solution set of a linear inequality?

Back

The solution set of a linear inequality is the set of all points that satisfy the inequality, often represented as a shaded region on a graph.

Front

How do you determine the boundary line of a linear inequality?

Back

The boundary line is determined by converting the inequality into an equation (e.g., replacing < with =).
