We can use vectors to create the vector equation of a line. In order to create the vector equation of a line we use the position vector of a point on the line and the direction vector of the line. In order to find the direction vector we need to understand addition and scalar multiplication of vectors, and the vector equation of a line can be used with the concept of parametric equations.
This video takes you through the formula to find the vector equation of a line and shows two examples.
