Assume a1/b11>a2/b21 and note that this implies that E4 lies in the first quadrant. Examine the type/stability of each of the four equilibria.

Plot the system's phase portrait within the first quadrant.
Please note that the plotting ranges xmax
and ymax
from the previous project will almost certainly be wrong choices here.
Apply your judgment to
choose a plotting region in the x-y plane which best shows
the behavior of the orbits near E4.
Plot the nullclines first to get an idea where to focus your
attention.
