This example illustrates how to graph horizontal and vertical lines and explains their slopes. Using GeoGebra commands such as Line, Point, Angle, and Intersect, these basic geometric objects can be constructed. Suitable for students in middle school and above to learn about linear equations and geometric construction.

GeoGebra Commands & Parameters

  1. Line(A, xAxis) → a
  2. Line(A, yAxis) → b
  3. Point(b) → B
  4. Point(a) → C
  5. Angle(B, A, C) → α
  6. Point(b) → D
  7. Intersect(b, xAxis) → E
  8. Intersect(a, yAxis) → F
  9. Intersect(b, a) → J
