Vector Equations of the Line

This example demonstrates dynamically generating lines by altering vector parameters s, u, and v. Core math concepts include vector equations, coordinate geometry, and linear transformations. Construction involves commands like Vector to create vectors A, B, u, C, D, and parameters s, sv for linear combinations, with interactive elements button1, text1, text2. Suitable for high school and above students learning vector and line equations, or for mathematical instruction.
