This is how you can accomplish your goals. shown below are one of the answer and question example that you can certainly work with to practice and improve your practical knowledge and also give you insights that might just assist you to sustain your study in school.

## Question:

A delivery truck has 40,000 miles on its odometer and travels an average of 22,000 miles per year. Which function best models the linear relationship? y = 22,000x − 40,000 y = –22,000x + 40,000 y = 22,000x + 40,000 y = 40,000x − 22,000

The function that best models the linear relationship will be y = 22,000x + 40,000.

Let the number of years be represented by x.

From the information given, the delivery truck has 40,000 miles on its odometer and travels an average of 22,000 miles per year, this will then be;

y = 40000 + (22000 × x)

y = 40000 + 22000x

Therefore, the function that best models the linear relationship will be y = 22,000x + 40,000.
