Topic: Linear Systems
Students determine whether points are in a region, on the boundary but not in the region, or not in the region of a system of inequalities.

Students will use an interactive Graphs & Geometry screen to determine the region representing a system of inequalities. When they move the point around the screen, the point will show up three different ways representing a point not in the region, a point on the boundary but not in the region, and a point in the region.
When students have finished identifying the points in the region, they will make a conjecture as to the system of inequalities. In the function line, they will enter the two inequalities that will define the region. If their conjecture is correct, the intersecting region will correspond with the classifications of the points.
