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 graph of a linear inequality represent?

Back

The graph of a linear inequality represents all the solutions to the inequality, which are the points that satisfy the inequality.

How do you determine if a point is a solution to a linear inequality?

Back

To determine if a point is a solution, substitute the x and y values of the point into the inequality. If the inequality holds true, the point is a solution.

What is the difference between a solid line and a dashed line in the graph of a linear inequality?

Back

A solid line indicates that points on the line are included in the solution (<= or >=), while a dashed line indicates that points on the line are not included (< or >).

What is the significance of the inequality symbol in a linear inequality?

Back

The inequality symbol indicates the relationship between the two expressions and determines which side of the line is included in the solution set.

How can you express the solution set of a linear inequality?

Back

The solution set can be expressed in interval notation, set notation, or graphically on a coordinate plane.
