根据两点写线性方程（y轴截距非整数）

GeoGebra 命令及参数

1. Sequence(i, i, -10, 10, 1) → ylist, {-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
2. Sequence(i, i, -10, 10, 1) → xlist, {-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
3. RandomElement(xlist) → a
4. Sequence(i, i, a + 1, 10, 1) → xlist2, {4, 5, 6, 7, 8, 9, 10}
5. Sequence(i, i, -10, a - 1, 1) → xlist1, {-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2}
6. Union(xlist1, xlist2) → list1
7. RandomElement(list1) → c
8. RandomElement(ylist) → b
9. RandomElement(ylist) → d
10. FractionText(e) → text1
11. Textfield(i) → InputBox1
12. FractionText(g(0)) → text8
