I was given an problem where i had to find the general solution then draw a phase portrait, then classify the origin and determine the stability of the system. I solved for the general solution but i have no idea how to do the other parts

general solution is

x=c_1(1,1)e^2t+c_2*(1,-4)*e^-3t (1,1 and 1,-4 are both 1 column 2 row matrices, i am not sure how to create a matrix on this forum)
