这是一个用于绘制线性方程的互动练习，通过斜率和截距提供即时反馈。它使用了GeoGebra中的Line, FractionText, Intersect, Polygon, Segment等命令，帮助学生理解线性方程的图形表示。适合初中及以上学生使用。

GeoGebra 命令及参数

  1. Sequence(i, i, -10, -1) → a, {-10, -9, -8, -7, -6, -5, -4, -3, -2, -1}
  2. Sequence(i, i, -10, -1) → b, {-10, -9, -8, -7, -6, -5, -4, -3, -2, -1}
  3. Sequence(i, i, 1, 10) → c, {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
  4. Union(b, c) → d
  5. Random(-12, 12) → e
  6. Line(A, B) → g
  7. FractionText(Slope[f]) → text1
  8. FractionText(f(0)) → text2
  9. Intersect(p, eq1) → C
  10. Polygon(A, C, B) → t1, b_1, a_1, c_1
  11. Segment(A, C) → i
  12. Segment(C, B) → j
  13. Segment(B, A) → k
