SOL Review Materials
The student will determine optimal values in problem situations by identifying constraints and using linear programming techniques.
Essential Knowledge and Skills 
  • Model practical problems with systems of linear inequalities.
  • Solve systems of linear inequalities with pencil and paper and using a graphing calculator.
  • Solve systems of equations algebraically and graphically.
  • Identify the feasibility region of a system of linear inequalities.
  • Identify the coordinates of the corner points of a feasibility region.
  • Find the maximum or minimum value for the function defined over the feasibility region.
  • Describe the meaning of the maximum or minimum value within its context.
Essential Understandings
  • Linear programming models an optimization process.
  • A linear programming model consists of a system of constraints and an objective quantity that can be maximized or minimized.
  • Any maximum or minimum value will occur at a corner point of a feasible region.
