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 one hour one and a half hours two hours two and a half hours and then here it shows hours of screen time so for example looks like Lu yang did zero hours of exercise did no exercise and spent seven hours in front of a screen not something that I would recommend and it looks like Kavita at half an hour had half an hour of exercise on Thursday this is all describing what happens on Thursday and at five and a half hours of screen time you see that right over there and 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 a I think that's how I would pronounce that so Maxime a is right over here and it looks like this is the point one because our horizontal coordinate right over here is one and then our vertical coordinate is 4 so point 1 comma 4 and this one is the hours of exercise so max you may exercise is 1 hour one hour exercise and they spend four hours in front of a screen on that Thursday four hours screen time screen time all right so let's see which of these choices say that let's see it is Maxie Maxie may had one hour of exercise in 4 hours of screen time yep this looks exactly right and if you just wanted to check the other ones Maxie may had two hours of exercise two hours of exercise in 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 and actually they had 4 hours of exercise in one hour of screen time 4 hours of exercise it's not even on this on we'd have to go off the screen so we'd rule that one out next we had 5 hours exercise once again that's not even on the screen here so that is so we can rule all of them out the third choice they're actually trying to confuse you because they're swapping the hours of exercise in screen time maxima has one hour of exercise four hours of screen time not four hours of exercise in one hour screen died
