Let's try this one. If one student studied for one hour more than another student, the student who studied more got exactly 15 more points on the test. Well, this is getting closer to the spirit of what the slope means, but this word exactly is what, at least in my mind, messes this choice up. Because this isn't saying that it's guaranteed that if you study an hour extra that you'll get 15% more on the test. This is just saying that this is the general trend that this line is seeing. So it's not guaranteed. For example, we could find this student here who studied exactly two hours, and if we look at the students who studied for three hours, well, there's no one exactly at three hours, but some of them, so this was, let's see, the student who was at two hours, you go to three hours, there's no one exactly there, but there's gonna be students who got better than what would be expected and students who might get a little bit worse.
