This slope also looks like positive one, so I can rule that one out. This slope at two comma two actually does look like zero, so I'm liking this one right over here. This slope at two comma two looks larger than one, so I could rule that out. So it was that straightforward to deduce that this choice right over here is, if any of these are going to be the accurate slope field, it's this one. But just for kicks, we could keep going to verify that this is indeed the slope field. So let's think about what happens when x is equal to, well, one, whenever x is equal to y, you're going to get the derivative equaling zero, and you see that here. When you're at four, four, derivative equals zero.
