Its a system of nonlinear differential equations. I would really appreciate the help.
Thank you.
Sure, no problem.
Beyond that, might also look here:

Or, in general, search online for 'wolfram phase diagram' for more things to help you find relevant items (there is a lot more resources available to you in this area, including on https://demonstrations.wolfram.com )
Ok thank you for your time.
That should open a Wolfram Cloud notebook:
Does this answer your question?
On the main website (not the mobile, I think) you can click the 'Open Code' button:
It helped. Do you know of any other way to plot this?
That is not correct Wolfram Language syntax.
If you are beginning to learn the Wolfram Language syntax, this is a good place to start:

Let me know if this helps you or not.
I've tried stream plot (y*(1-y^2),x) but I don't know if this is the correct way of doing it.
What have you tried so far?
