Exam points

  • Draw each straight boundary accurately, using solid lines for inclusive inequalities and broken lines for strict inequalities.
  • Shade the unwanted side of every boundary so that the remaining feasible region R satisfies all inequalities.
  • Test feasible vertices or integer points to maximise a stated linear objective or profit.
