Expert Solution

For plotting phase potrait, the eigenvector corresponding to the eigenvalue is pointed and then a line is drawn through that point which crosses origin. If the eigenvalue is negative then it goes into the origin. Then, select the most negative eigenvalue and draw a curve parallel to it's line and while it reaches origin, converge it to the origin. This is the phase potrait.
