Interpreting plotted points

The graph below shows the relationship between hours of exercise and hours of screen time for a group of five friends on Thursday. So if we look over here, we can see that here on this horizontal axis, when we're going from the left to right, it says hours of exercise: so half an hour, 1 hour, 1 and a half hours, 2 hours, 2 and 1 half hours.

Then here it shows hours of screen time. For example, it looks like Le Yang did zero hours of exercise, did no exercise, and spent seven hours in front of a screen. Not something that I would recommend. It looks like Cava spent half an hour; had half an hour of exercise on Thursday—this is all describing what happens on Thursday—and had 5 and a half hours of screen time. You see that right over there?

We could keep going with all the other data points, but let's see what they're asking us. What is the meaning of the point marked Maxime? I think that's how I would pronounce that. So, Maxime is right over here, and it looks like this is the point (1, 4) because our horizontal coordinate right over here is 1, and then our vertical coordinate is 4.

So point (1, 4) is the hours of exercise, so Maxime's exercise is 1 hour—1 hour of exercise—and they spend 4 hours in front of a screen on that Thursday: 4 hours screen time.

All right, so let's see which of these choices say that. Let's see, it is: Maxime had 1 hour of exercise and 4 hours of screen time. Yep, this looks exactly right! If you just wanted to check the other ones: Maxime had 2 hours of exercise and 8 hours of screen time—that would put them way up here, and that's not where the point was, so we'd rule that out.

Maxime had 4 hours of exercise and 1 hour of screen time. Four hours of exercise is not even on this; we’d have to go off the screen, so we’d rule that one out. Maxime had 5 hours of exercise—once again, that’s not even on the screen here, so that is so we can rule all of them out.

This third choice, they’re actually trying to confuse you because they’re swapping the hours of exercise and screen time: Maxime has 1 hour of exercise, 4 hours of screen time—not 4 hours of exercise and 1 hour of screen time!
