Question

A study shows that as the temperature decreases, the electric bill increases. Which graph best represents this situation?

Answer 1

The only graph whose line is strait

Explanation:

This graph represents the situation because energy bills will have a set amount of money which directly correlates with the amount of energy you use. When it gets cold you use more energy to keep you warm. As you use more energy your price rises at the same pace-thus a strait line.
