Answer:
The relationship is not proportional
Step-by-step explanation:
A relation is proportional if the division of the respective values of the variables is constant.
In this case, it is proportional if the Puppy's Weight Gain divided by the number of weeks is always the same. So:
12/4 = 3
9/3 = 3
4/2 = 2
Since 2 is distinct, the relationship is not proportional.
