This example demonstrates the graphical representation of basic linear inequalities. Key mathematical concepts include inequalities and coordinate geometry. It uses commands like Random, Point, DynamicCoordinates, and Vector in GeoGebra. Suitable for middle school and above students to learn how to graph inequalities.

GeoGebra Commands & Parameters

  1. Random(-10, 10) → a
  2. Point(Segment[(-10, 1), (10, 1)]) → A
  3. Random(1, 4) → e
  4. Random(0, 1) → r
  5. DynamicCoordinates(A, round(x(A)), 1) → B
  6. Vector((x(B) + 0.4, 1), (11, 1)) → u
  7. Vector((x(B) - 0.4, 1), (-11, 1)) → v
