This example demonstrates postal rate calculations using linear regression models and data points. It involves core math concepts like linear regression, linear functions, confidence intervals, and optimization problems. Constructed with GeoGebra commands such as Segment, Line, Point, Polygon, RotateText, and Textfield. Suitable for high school and above, focusing on data analysis and function modeling.

GeoGebra Commands & Parameters

  1. Segment(A, B) → f
  2. Line(M, xAxis) → g
  3. Point(g) → N
  4. Segment(K, L) → i
  5. Segment(I, J) → j
  6. Segment(G, H) → k
  7. Segment(E, F) → l
  8. Polygon((0, 0), (30, 0), (30, 10), (0, 10)) → poly1, h, n, p, q
  9. Segment(C, D) → m
  10. Segment(M, O) → s
  11. RotateText(text2, 90°) → text3
  12. Textfield(f_1) → InputBox1
  13. Textfield(f_2) → InputBox2
  14. Textfield(f_3) → InputBox3
  15. Textfield(f_4) → InputBox4
