This example demonstrates how to use GeoGebra to draw parallel and perpendicular lines and solve related mathematical problems. The core math concepts involved include equations, straight lines, upper and lower sum or Riemann sum, Pythagoras or Pythagorean Theorem, inequalities, step functions, and linear programming or linear optimization. The construction highlights the use of GeoGebra commands and objects such as m_1, c_1, a, m_2, c_2, b, m_3, c_3, c, m_4, c_4, d. It is suitable for high school students learning coordinate geometry.

GeoGebra Commands & Parameters

  1. Numeric m_1(-4.5)
  2. Numeric c_1(-2)
  3. y = (m_1 * x) + c_1
  4. Numeric m_2(0.5)
  5. Numeric c_2(0.9)
  6. y = (m_2 * x) + c_2
  7. Numeric m_3(-1)
  8. Numeric c_3(-2.9)
  9. y = (m_3 * x) + c_3
  10. Numeric m_4(1)
  11. Numeric c_4(5)
  12. y = (m_4 * x) + c_4
