In collections A1.ACE.1 - Create and solve equations and inequalities Linear Inequalities
This example demonstrates a dynamic visualizer for interval notation used with basic linear inequalities. It covers core math concepts like interval notation, linear inequalities, and set operations. Constructed using GeoGebra commands like Segment and Ray, involving objects such as f, a, b, A, B, g, C, D, etc. Suitable for middle school and above students learning to visualize and manipulate solution sets of inequalities.

GeoGebra Commands & Parameters

  1. Segment(A, B) → g
  2. Segment((x(A) + 0.3, 1), (x(B) - 0.3, 1)) → j
  3. Ray((x(A) - 0.3, 1), (x(D), y(D))) → i
  4. Ray((x(B) + 0.3, 1), (x(C), y(C))) → h
  5. Ray((x(A) + 0.3, 1), (x(C), y(C))) → k
