This example demonstrates representing and solving inequalities on a number line. It involves core math concepts like inequalities, number line representation, and linear equation solutions. Construction uses GeoGebra commands/objects such as Random, Point, DynamicCoordinates, Vector for dynamic point generation and vector visualization, showing inequality ranges. Suitable for middle school and above students learning inequality concepts and geometric interpretation of mathematics.

GeoGebra Commands & Parameters

  1. Random(-10, 10) → a
  2. Point(b) → A
  3. Random(1, 4) → e
  4. Random(0, 1) → r
  5. DynamicCoordinates(A, round(x(A)), 1) → B
  6. Vector((x(B) + 0.15, 1), (11, 1)) → u
  7. Vector((x(B) - 0.15, 1), (-11, 1)) → v
