函数解析几何导数
①本范例演示线性函数的变化率（斜率）计算与可视化；②涉及核心数学概念：线性函数、斜率、坐标几何；③作图要点：使用了Random, Line, Textfield, Polygon, LaTeX, Sequence, TableText等GeoGebra命令与对象；④适合高中数学教学，用于理解函数图像与斜率关系。

GeoGebra 命令及参数

  1. Random(-10, 10) → n_1
  2. Line(B, A) → a
  3. Textfield(deltay) → InputBox2
  4. Random(-5, 5) → m
  5. Random(-10, 10) → n
  6. Textfield(b) → InputBox3
  7. Textfield(g) → InputBox1
  8. Polygon(C, D, E, F) → poly1, c_1, d, e, f_1
  9. LaTeX(deltax_1, true, true) → text10
  10. LaTeX(intersecty, true, true) → text11
  11. LaTeX(deltay_1, true, true) → text12
  12. Sequence(((deltax * i), intersecty + (deltay_1 * i)), i, -20, 20) → list1
  13. Sequence(Segment[A + ((deltax * (i + 1)), (deltay_1 * i)), A + ((deltax * (i + 1)), (deltay_1 * (i + 1)))], i, -20, 20) → rises
  14. Sequence(Segment[A + ((deltax * i), (deltay_1 * i)), A + ((deltax * (i + 1)), (deltay_1 * i))], i, -20, 20) → runs
  15. Textfield(i) → InputBox4
  16. LaTeX(deltax, true, true) → text6
  17. Random(-3, 3) → j
  18. TableText({{p, k, k_1}, {A2, B2, C2}, {A3, B3, C3}, {A4, B4, C4}, {A5, B5, C5}, {A6, B6, C6}, {A7, B7, C7}, {A8, B8, C8}}, "|_lll") → text2
