WebGraph a linear inequality in two variables. Step 1. Identify and graph the boundary line. If the inequality is ≤ or ≥, the boundary line is solid. If the inequality is < or >, the boundary line is dashed. Step 2. Test a point that is not on the boundary line. Is it a solution of the inequality? Step 3. Shade in one side of the boundary line. WebSimilarly, linear inequalities in two variables have many solutions. Any ordered pair that makes an inequality true when we substitute in the values is a solution to a linear inequality. Solution to a Linear Inequality. An ordered pair is a solution to a linear inequality if the inequality is true when we substitute the values of x and y. imshow picture
