Let w be the number of worms (in millions) and r the number of robins (in thousands)

Question:

Let w be the number of worms (in millions) and r the number of robins (in thousands) living on an island. Suppose w and r satisfy the following differential equations, which correspond to the slope field in Figure 9.44.
