Testing and 4-4 Linear Inequalities in Two Variables – We learned that the graph of a linear inequality in two variables shows the solutions of the inequality as a half-plane above or below the boundary line. Then we learned that the boundary line is included in the solution when the inequality symbol is less than or equal to or greater than or equal to. The boundary line in an inequality is excluded when the inequality symbol is less than or greater than.
