Key Concepts

Number Line Graphing

Graphing an inequality on a number line is a basic technique for visually representing the solution set. It involves marking the pertinent points on the number line and shading the correct side that corresponds to the inequality, making it easier to see which values satisfy the inequality.

Open and Closed Endpoints

When graphing inequalities, identifying whether an endpoint is included in the solution is crucial. For strict inequalities (using < or >), an open circle is used to show that the endpoint is not part of the solution set; for inclusive inequalities (using ? or ?), a closed or filled-in circle is used to indicate that the boundary value is included.

Linear Inequalities

This concept involves expressions using inequality symbols (like <, >, ?, or ?) to compare linear expressions. Understanding linear inequalities is essential for determining the range of values that the variable can take based on the direction of the inequality.
