Before we explain the definition of the dependent and independent variable, let’s test your knowledge!

Lyla commits to head outside 8 times as much as she spends indoor. **X **symbolizes the amount of time spent indoor, whereas** y** symbolizes the time spent outdoors.

y=8x **Identify the dependent variable in the equation**.

If you guessed y, you’re correct! But do you know why** y **is the dependent variable? **Y** is the **dependent variable** because the value of it changes because of x.

Let’s say Lyla spent 5 hours indoors. Because she spent 5 hours indoors, the amount of time spent outside would result because of the decision. Think of it as a cause and effect. The cause would be the value of x, which shifts the value of y. In summary, y acts as a **result** of a decision/value.

**Too confusing? Here’s a definition from google.com: **

The **independent variable** is the cause… Its value is **independent** of other **variables** in your study. The **dependent variable** is the effect. Its value depends on changes in the **independent variable**.

Now that you understand the definition of a dependent and independent variable, try some questions on your own.

Rylie starts a bake sale, selling only brownies. For every brownie she sells, her school gives her $10. B stands for the number of brownies she sells. M stands for the money she makes.

m=10b ** Identify the independent variable.**

The correct answer is** b**.

B effects the variable m, meaning that B is the independent variable.

Wyatt makes a deal with his mother. She agrees to give him 10 dollars if he does all his chores. For each chore Wyatt does, he get’s 5 dollars. C stands for the amount of chores he does. M stands for the money he has in total.

m=10+5c Identify the dependent variable.

The correct answer is **m**.

**M**‘s depends on the change of c.

Good job learning about dependent and independent variables! Hopefully, you can identify the two in different situations and equations.

If I were a variable, I think I like to be independent. I like to have the freedom to do as I want and not be tied down to another variable.
