FunctionCoordinate GeometryGeometric Construction
This example demonstrates how to draw a line through two points and calculate its slope, covering core math concepts like the slope formula and coordinate geometry. It uses GeoGebra commands such as Sequence, RandomElement, Union, FractionText, and Textfield, with objects like ylist, xlist, a, xlist2, xlist1, list1, c, b, d, e, text1, text2, text5, f, InputBox1, button1, text3, text4, text6, text7. Ideal for high school students learning analytical geometry.

GeoGebra Commands & Parameters

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