This example demonstrates the rate of change of a linear function. Key mathematical concepts include linear functions, slope, and linear equations. Using GeoGebra commands such as Random, Line, and Textfield, the slope changes dynamically. Suitable for students in middle school and above to learn about linear functions.

GeoGebra Commands & Parameters

  1. Random(1, 5) → deltax_2
  2. Line(B, A) → a
  3. Textfield(deltax) → InputBox1
  4. Textfield(deltay) → InputBox2
  5. Textfield(b) → InputBox3
  6. Sequence(((deltax * i), b + (deltay * i)), i, -20, 20) → list1
  7. Sequence(Segment[A + ((deltax * (i + 1)), (deltay * i)), A + ((deltax * (i + 1)), (deltay * (i + 1)))], i, -20, 20) → rises
  8. Sequence(Segment[A + ((deltax * i), (deltay * i)), A + ((deltax * (i + 1)), (deltay * i))], i, -20, 20) → runs
  9. Polygon(C, D, E, F) → poly1, c_1, d, e, f
  10. LaTeX(m, true, true) → text10
  11. LaTeX(n, true, true) → text11
  12. Random(1, 5) → deltax_1
  13. Textfield(h) → InputBox4
  14. TableText({{p, k, l}, {A10, B10, C10}, {A11, B11, C11}, {A12, B12, C12}, {A13, B13, C13}, {A14, B14, C14}}, "|_r") → text2
