Ch 5 — Linear Inequalities
Solve linear inequalities in one variable algebraically and show solution sets on the number line. Two-variable inequalities sketch half-planes for graphical solutions.
Solution sets on the line and plane
Solve linear inequalities in one variable algebraically and show solution sets on the number line. Two-variable inequalities sketch half-planes for graphical solutions.
- Treat = as a boundary line; shade the true side with a test point.
- Systems of inequalities: intersection of half-planes (feasible region).
