So we could rule this one out as well. And so we should feel pretty confident that this is the differential equation being described. And now that we've done it, we can actually think about, well okay, what are the solutions for this differential equation going to look like? Well it depends where they start, if you have, or what points they contain. If you have a solution that contains that point, it looks like it might go, looks like it might do something, looks like it might do something like, something like this. If you had a solution that contained, I don't know, if you had a solution that contained this point, it might do something, it might do something like that. And of course it keeps going, it looks like it would asymptote towards y is equal to negative x, this downward sloping, this essentially is the line y is equal to negative x.
