Once again, for this magenta differential equation, if x and y are both equal to one, then one minus one is once again going to be equal to zero. And we've already seen the slope is not zero here. So rule that one out. And now here we have x plus y. So when x is one, y is one, the derivative of y with respect to x is going to be one plus one, which is equal to two. Now this looks interesting. It looks like this slope right over here could be two.
