A botanist wants to plant certain types of oak trees and pine trees in a $600$-foot-long row. Each of these oak trees requires $40$ feet of space to grow, and each of these pine trees requires $30$ feet of space to grow. The equation $40x+30y=600$ models the possible number of oak trees, $x$, and pine trees, $y$, that the botanist can plant. Which graph represents this relationship?

A

Graph with intercepts $(15,0)$ and $(0,20)$

B

Graph with intercepts $(20,0)$ and $(0,15)$

C

Graph of a line with a positive slope

D

Graph with intercepts $(10,0)$ and $(0,10)$
