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 a dashed boundary line indicate in graphing linear inequalities?

Back

A dashed boundary line indicates that the points on the line are not included in the solution set, which occurs when the inequality does not have an 'or equal to' component.

What does a solid boundary line indicate in graphing linear inequalities?

Back

A solid boundary line indicates that the points on the line are included in the solution set, which occurs when the inequality has an 'or equal to' component.

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 part of the solution set.

What is the solution set of a linear inequality?

Back

The solution set of a linear inequality is the set of all points (x, y) that satisfy the inequality, represented graphically as a shaded region on the coordinate plane.

What is the significance of the inequality symbol in graphing?

Back

The inequality symbol determines whether the boundary line is dashed or solid and indicates which side of the line is included in the solution set.

What is the first step in solving a linear inequality?

Back

The first step is to isolate the variable on one side of the inequality, similar to solving a linear equation.

Substitute the point's coordinates into the inequality. If the resulting statement is true, the point is part of the solution set.
