1
Solving Systems of Inequalities: 3 - 4
You will simply be graphing two inequalities on the same graph. The solution will be a section of the graph, not a point.
2
Solving Systems of Inequalities
PWS 3-4 (on ibooks) Graph the inequalities y + 1 < -x and y ≥ 1. The solution is the section of overlap.
3
Solving Systems of Inequalities
To graph a system of inequalities using the calculator, just plug in the two inequalities and graph. Make sure you use the correct inequality for each one. (Type, F6, F1-F4)
4
Solving Systems of Inequalities
From your two inequalities, you should get a region of the graph that is double shaded. (you may want to use different colors or means of shading for each inequality)
5
Solving Systems of Inequalities
This region is your solution. What does this mean? Any point in this double-shaded region would solve BOTH equations!!!
