Question: If each state variable in a system of autonomous differential equations does not respond to changes in the value of the other, but depends only

If each state variable in a system of autonomous differential equations does not respond to changes in the value of the other, but depends only on a constant value, the two equations can be considered separately. In this case, the phase plane is particularly simple. Find the null clines and equilibria in the following cases.
1. The situation in Section 5.5, Exercise 5.
2. The situation in Section 5.5, Exercise 6.
