Section 2.7 – Graphing Two-variable Inequalities Warm-up Focus : Solve each one-variable inequality (and graph) 1) 9 2 7 1 < + x 2) 11 1 2 + x 3) -3 < x + 3 < 8 Objectives - Graph linear inequalities in two variables. - Graph absolute variable inequalities in two variables. A linear inequality is an inequality in two variables whose graph is a region of he coordinate plane that is bounded by a line. To graph a linear inequality: 1. Graph the boundary line 2. Decide which side of the line contains solutions to the inequality 3. Decide whether the boundary line is included. 1) Graph the inequality 2 3 - - < x y

2) Now you try! Graph 30 5 3 + y x 3) An air cargo plane can transport as many as 15 regular shipping containers.

Unformatted text preview: One super-sized shipping container takes up the space of 3 regular containers. a. Write an inequality to model the situation and graph it. b. If there are already 2 super-sized shipping containers on the plane, can we fit 8 more regular sized shipping containers? To graph absolute value inequalities, we follow the same steps as before. 4) Graph 1 3 + +-x y You try! 5) 4 2 3--x y Now that you are able to graph two variable inequalities, can you figure out what equation goes with a graph? 6) HW #__ Page 102 (2-6 even, 1517, 38 40 even, 45)...
