High school — Graph the solutions to a linear inequality in two variables as a half-plane, and the solution set of a system of linear inequalities as the intersection of half-planes.
The skill that covers it
What a student should be able to do
- Decide whether a point is a solution of a linear inequality in two variables, or of a system.
- Match a shaded graph to its inequality, choosing the boundary style and the side to shade.
- Describe the solution region of a system of two linear inequalities.
- Write a system of inequalities from the constraints of a word problem.
