This right over here shows, or like this one over here is a student who says they studied two hours, and it looks like they scored about a 64 or 65 on the test. And this over here, or this over here, looks like a student who studied over four hours, or they reported that, and they got, looks like a 95 or a 96 on the exam. And so then, and these are all the different students, each of these points represents a student, and then they fit a line. And when they say which of these linear equations best describes the given model, they're really saying which of these linear equations describes or is being plotted right over here by this line that's trying to fit to the data. So essentially, we just wanna figure out what is the equation of this line? Well, it looks like the y-intercept right over here is 20, and it looks like all of these choices here have a y-intercept of 20, so that doesn't help us much. But let's think about what the slope is.
