Kiara measured the weight of her dog at the end of every month. She used a line graph to display the data.

Between which two months did the dog grow the most?

Jane measured the weight of her kitten at the end of every month. She used a pictograph and a line graph to display the data.

In which two months did the kitten grow at the same rate? Which graph shows this more clearly?

The line graph is given below shows the sales of a shopkeeper in the first week of January $2016$.
