So already I could rule this one out. This slope right over here looks like it's positive one, so I'll rule that out. It's definitely not zero. 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.
