This document provides instructions for graphing inequalities on a coordinate plane. It begins by graphing examples of inequalities on a number line and plane. It then explains how to graph linear inequalities by writing them as equations, making a table of x-y values, plotting the points, and drawing the boundary line. Examples are provided of graphing inequalities in slope-intercept form such as y ≥ -3x + 2. The document also covers testing points, determining whether to shade above or below the line, and applying the process to graph more complex inequalities like 3x - 4y > 12. It concludes with an example of using inequalities to model real-world constraints and find maximum/minimum values through optimization
