Students learn to graph inequalities in two variables For example, to graph y x 2, the first step is to graph the boundary line y = x 2, using the chart method from lesson 4BNote that greater than or less than means that the boundary line will be dotted, and greater than or equal to or less than or equal to means that the boundary line will be solidSolution Step 1 First graph 2x y = 4 Since the line graph for 2x y = 4 does not go through the origin (0,0), check that point in the linear inequality Step 2 Step 3 Since the point (0,0) is not in the solution set, the halfplane containing (0,0) is not A linear inequality is an inequality that can be written in one of the following forms A x B y > C A x B y ≥ C A x B y < C A x B y ≤ C Where A and B are not both zero Recall that an inequality with one variable had many solutions For example, the solution to the inequality x>3x>3 is any number greater than 3
