Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

This step will be repeated for the remaining figure.

Question 2:

As an be seen from the scatter plot, price per quart decrease when the number of quarts increase so the relation between the two variable show a negative association

Hope it will find you well.
