This example demonstrates the graphical representation of one-variable linear inequalities. Key mathematical concepts include one-variable linear inequalities and their solution sets. Using GeoGebra commands such as RandomElement, Random, and If, the solution set can be dynamically displayed. Suitable for middle school and above students to learn the solution methods and geometric representations of inequalities.

GeoGebra Commands & Parameters

  1. RandomElement({1, 2}) → LR
  2. Random(1, 10) → m
  3. Random(-20, 20) → b
  4. Random(-50, 50) → c
  5. If(LR ≟ 1, (m * x) + b, c) → L
  6. If(LR ≟ 2, (m * x) + b, c) → R
  7. RandomElement({L(x) > R(x), L(x) ≥ R(x), L(x) < R(x), L(x) ≤ R(x)}) → ineq
  8. Polygon({(-1000, 12), (-1000, 14), (1000, 14), (1000, 12)}) → poly1
  9. Segment(A, (0, -0.16)) → e
  10. Textfield(n) → inputBox1
