Question

The weight, in pounds, of a newborn baby t months after birth can be modeled by the equation w=2t+12. What is the slope of the equation, and what is its interpretation in the context of the problem?

a. Slope: 2, Interpretation: The baby gains 2 pounds each month.
b. Slope: 2, Interpretation: The baby's weight is 2 pounds.
c. Slope: 12, Interpretation: The baby gains 12 pounds each month.
d. Slope: 12, Interpretation: The baby's weight is 12 pounds.

Answer 1

The slope of the equation is 2, meaning the baby gains 2 pounds each month.

Step-by-step explanation:

The equation w=2t+12 represents the weight of a newborn baby, with w being the weight in pounds and t being the time in months after birth. The slope of the equation is 2, which means that for every increase of 1 month, the baby's weight increases by 2 pounds. Therefore, the correct answer is (a) Slope: 2, Interpretation: The baby gains 2 pounds each month.
