Parametric Equations of a Line

---

In this video I convert the vector equation of a line into its parametric equations form. To do this I first expand the vector equation by writing out its components and then summing them up. Then I equate each x, y, and z coordinate with its corresponding components resulting in 3 equations. These 3 equations are called the Parametric Equations of a line. I also go over an example on finding the vector and parametric equations of a line that passes through the point (5, 1, 3) and is parallel to the vector [1, 4, -2]. Finally, I graph the line using the amazing GeoGebra 3D graphing calculator, which you can play around with here: https://www.geogebra.org/calculator/wszwnpme
