Vector, Parametric, and Symmetric Equations of a Line

---

In this video I go over the the 3 main equations of a line in 3D: vector equation, parametric equations, and symmetric equations. The vector equation defines a line as a vector to a point on the line and is comprised of a vector to any point on the line plus any parallel vector to the line. The parametric equations of a line separates the x, y, z components of the vector equation of a line into their own separate equations. The symmetric equations of a line solves for the parameter in the parametric equations and equates them for all 3 equations.
