The situation that can be modeled by a linear function is:

The employees at a local hardware store earn a $2-per-hour wage increase every year they work for the company.

This is because the wage increase is a constant amount added to the employees' earnings for each year they work, creating a linear relationship between years worked and their hourly wage.
