Explanation:
- In the question, it is given that a problem uses an input variable.
- It is required to explain how to find the input variable in a word problem that uses a linear function.
- In order to find the input variable in a world problem, seek for the independent variable.
- That is a value that does not depend on any other value and it can change independently.
- Some other values change based on that value. In these types of functions, this value is mostly marked as x.
