medium

A group of $10$ gardeners recorded data on the germination rates of their tomato crop for one growing season. The scatterplot shows the relationship between the number of tomato seeds planted, $x$, and the number of tomato seeds that germinated, $y$, for each of the gardeners. A line of best fit is also shown. Which of the following is the best interpretation of the slope of the line of best fit in this context?

A

The number of tomato seeds planted is predicted to increase by $60$ seeds every $100$ days.

B

The number of tomato seeds planted is predicted to increase by $300$ seeds every $100$ days.

C

The number of tomato seeds that germinate is predicted to increase by $60$ seeds for every additional $100$ tomato seeds that are planted.

D

The number of tomato seeds that germinate is predicted to increase by $300$ seeds for every additional $100$ tomato seeds that are planted.
