# Dependent and independent variables

1 skill
We know that anything that is "independent" is not affected by other "dependent" forces. In math relationships (and algebra, in particular), one variable (the independent one) is thought to drive the behavior of the other one (the dependent one). This tutorial explores that relationship and how it can be expressed and interpreted. Common Core Standards: 6.EE.C.9

### Dependent and independent variables exercise: the basics

VIDEO 2:10 minutes
Here we have a problem that asks us to identify which variables are dependent and independent. Hint: independent variables are not influenced and remain unchanged by the other variable.

### Dependent and independent variables exercise: graphing the equation

It's helpful to express an equation on a graph where we plot at least 2 points. Watch and we'll show you.

### Dependent and independent variables exercise: express the graph as an equation

VIDEO 2:00 minutes
We're flipping the last video on its head and doing the opposite. This time we give you the graph and ask you to express it as an equation.
