Represent the Solutions of a Linear Inequality or a System of Linear Inequalities Graphically as a Region of the Plane

If the solution to system of linear inequalities is a shaded region in a graph, what does this shaded region represent?

• The possible values that satisfy both inequalities

• The x-intercepts of the inequalities

• The impossible values that satisfy both inequalities

• The y-intercepts of the inequalities
