Description: Sal works through a word problem interpreting coordinates in the first quadrant on a coordinate plane. The graph below shows the relationship between hours of exercise and hours of screen time for a group of five friends on Thursday. So, for example, it looks like Liu Yang did zero hours of exercise, did no exercise and spent seven hours in front of a screen. And it looks like Kavitha spent half an hour, had half an hour of exercise on Thursday.
