## Parametric Equations

In this tutorial the students will learn about parametric equations and how they relate to rectangular equations. Parametric equations describe the location of an object at a specific point in time. Parametric equations include a time component. A rectangular equation, on the other hand, only describes the path that an object takes. Rectangular equations do not include the ability to tell where the object is located at a specific point in time.

Also, the students will learn how to convert a parametric equation to a rectangular equation by following a few easy steps in this 9 minute tutorial.

Finally, the students will find that the rectangular equation in this example is a **linear** equation or just a straight line with a positive slope.
