"Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.

When graphing a system of linear equations in two variables, the solution, if one exists, is the point where the two lines intersect. When graphing a system of linear inequalities, the solution isn't a point, but a "region." This region contains all the points that satisfy the system.

In this tutorial we will be looking at linear inequalities in two variables. It will start out exactly the same as graphing linear equations and then we get to color in the region of the coordinate system that correlates with the inequality.
