Motion Along a Line :
We can use the vector equation of a line to describe the motion along a line. We can also rewrite these equations to represent the motion along a line as a parametric equation. In order to create a vector equation or a parametric equation to describe the motion along a line we need to determine a starting position for time zero and a velocity.

Parametric Equations and Motion :
Sometimes when graphing a shape or equation we want to add a parameter, something like time, which requires us to use parametric equations. One example of the use of parametric equations is to describe the motion along a line. Parametric equations can also be used to describe line segments or circles. Parametric equations are represented by two functions of x and y dependent on t. How to graph a parametric curve, and how to eliminate the parameter to obtain a rectangular equation for the curve.
