Hi

I have managed to plot the phase portrait for the system

dx/dt = -4x(t) + y(t) + 2

dy/dt = 2x(t) - 2y(t) + 3

but i dont know how to plot the equilibrium lines

-4x + y + 2 = 0 and

2x - 2y + 3 = 0

on the same graph preferably in a different colour.

If anyone could help that would be great.

thanks
