For the first 3 years of a horse's life, the weight, w (in kilograms), of the horse approximately fits the formula w (t) = 30+170t, where t is the age of the horse in years. Which of the following is the most accurate interpretation of the slope of the line represented by this formula?

A. The slope is 170. This means that the horse gains an average of 170 kilograms per year for the first 3 years of its life.

B. The slope is 30. This means that the horse gains a total of 30 kilograms in the first 3 years of its life.

C. The slope is 30. This means the horse gains on average 30 kilograms per use for the first 3years of its life.

D. The slope is 170. This means that the horse gains a total of 170 kilograms in the first 3 years of its life.
