Parts B, E, F. I attached a photo of the answered parts. 

For the following systems, the origin is the equilibrium point.
dx
a) Write each system in matrix form = Ax.
dt
b)
Determine the eigenvalues of A.
c) State whether the origin is a stable or unstable equilibrium.
d) State whether the origin is a node, saddle point, spiral point, or center.
e) State the equations of the straight-line trajectories and tell whether they are going
towards or away from the origin. If none exist, state so.
f) If A has real eigenvalues, then determine the eigenvectors and use diagonalization to
solve the system. (See examples in Section 7.4)
