A newborn kitten weighs 3 ounces at birth. After four weeks, it weighs 13 ounces. Which of the following is true?
A. The kitten's age and weight are not in a proportional relationship because the difference in the weight of the kitten after four weeks is 10 ounces.
B. The kitten's age and weight are not in a proportional relationship because the weight of the kitten increases by 2.5 ounces every week.
C. The kitten's age and weight are not in a proportional relationship because the kitten does not weigh zero ounces at birth.
D. The kitten's age and weight are not in a proportional relationship because the weight of the kitten increases over time.

what do u think the answer is

Vocaloid · Answer

in order for a proportional relationship to be true, y = kx
(notice how the independent variable x is only being multiplied by k, not added or subtracted, etc.)

now, in a proportional relationship, if x = 0 then y must be 0 as well. does this also apply to the real life situation of the kitten weight?
