Question

Joshua is trying to decide if there is a relationship between a driver's age and the number of traffic tickets they get. He surveys 150 people in three towns and records their age, many traffic tickets they got in the last year, and the town they live in. He creates a graph of his data.

What is the independent variable?

Answer 1

Hello!

The number of tickets is dependent on age, so age is the independent variable.

Think of it as a y = mx equation. In this equation, x is the input, and y changes depending on the value of x inputted.

In this situation, y is the number of tickets, as y changes depending on the age x inputted. x is age, the independent variable.
