This example demonstrates how to graph linear inequalities with two variables using the slope-intercept form. Key math concepts include inequalities, slope-intercept equations, and function graphing. GeoGebra commands and objects used are Sequence, Union, Random, Line, FractionText, and Slope. Suitable for middle school and above students learning to represent linear inequalities graphically.

GeoGebra Commands & Parameters

  1. Sequence(i, i, -10, -1) → a
  2. Sequence(i, i, -10, -1) → b
  3. Sequence(i, i, 1, 10) → c
  4. Union(b, c) → d
  5. Random(-10, 10) → e
  6. Line(A, B) → i
  7. FractionText(Slope[f]) → text1
  8. FractionText(f(0)) → text2
  9. Random(1, 4) → symbol
  10. Line(A, B) → h
  11. Slope(i) → slope_i
