In collections C4 vectors
This example demonstrates how a line in 2D can be described using a position vector and a direction vector as an alternative to the slope-intercept form. It involves core mathematical concepts like vectors, line equations, slope, and coordinate geometry. Constructed using GeoGebra commands: Vector, Line, Intersect, Slope. Suitable for high school coordinate geometry teaching, helping students understand different forms of line equations and their applications.

GeoGebra Commands & Parameters

  1. Vector(B, C) → v
  2. Vector(A) → u
  3. Line(A, v) → a
  4. Intersect(a, yAxis) → D
  5. Slope(a) → m
  6. Vector(E) → r

AI Drawing Prompt Reference

Draw a 2D coordinate plane with a line defined by a position vector and a direction vector. Place two points, draw an arrow from one to the other as the direction vector, then draw the line through the starting point along that direction. Mark the intersection of the line with the y-axis. Also, from the origin, draw an arrow to a point on the line to represent the position vector. Label the slope of the line and show both the vector equation and slope-intercept equation of the line.
