The correct answer is - line graph.

Explanation:

The change in the weight of puppies of Janine and Rodney over the time period of six months can be determined by the line graph.

The line graph displays consecutive change by connecting points where change occurs. The graph can represent descend or ascend based on the data.

Thus, the correct answer is - line graph.
