Graphing Inequalities The graph of a linear inequality is a HALF-PLANE (or half of a coordinate plane) WARM-UP: Complete Problem 1 on pages 412 - 414

Objective - To graph systems of linear inequalities.

Determining a Solution Solutions to a system of inequalities are all the points in the double shaded region. You can always PLUG IN the given point into BOTH inequalities to determine if it is a solution. REMEMBER: The point must make BOTH inequalities TRUE to be a solution to the system.

Graph a system of 3 linear inequalities.

Write a system of linear inequalities that describe the shaded region. 1) 2)

Write a system of linear inequalities that describe the shaded region. 3) 4)
