2.2 Graphs of Linear Inequalities

Graphs of Single Variable Inequalities

  • Inequalities can be represented graphically as a shaded area.
  • For single variable inequalities, the shaded area is enclosed by two vertical (for x inequalities) or horizontal (for y inequalities) lines.

Example

Below is a graph representing the inequality -2 \leq x \leq 1:
