Key Concepts

Graphing Linear Inequalities

Graphing linear inequalities involves plotting the boundary line obtained by replacing the inequality symbol with an equality, and then shading the appropriate region of the plane that satisfies the inequality. This process visually represents all the points that meet the condition defined by the inequality.

Systems of Linear Inequalities

A system of linear inequalities includes multiple inequalities that must be solved simultaneously, and the solution is the intersection of all the individual regions defined by each inequality. This means that the overall solution set consists of the points that satisfy every condition in the system.

Cartesian Coordinate System

The Cartesian coordinate system, defined by a horizontal axis (x-axis) and a vertical axis (y-axis), is used to plot points and graph equations and inequalities. It provides a framework to visually interpret and analyze relationships between linear inequalities.

Boundary Lines

Boundary lines are the lines that are formed when an inequality is converted into an equation. They serve as the dividing lines between different regions of the coordinate plane and are drawn using a solid line if the inequality includes equality (e.g., ? or ?) or a dashed line if not.

Shading Regions

Shading regions in the graph of an inequality is a method used to illustrate the set of all points that satisfy the inequality. By testing a point not on the boundary, one can determine which side of the boundary to shade, highlighting the valid solution region.
