The graph displays research data relating the number of pages read per hour to the number of focused hours: the number of hours for which a reader could read at a given speed without beginning to lose focus. The line on the graph is a trendline representing the data.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided.
The data point for which the distance to the trendline is greatest corresponds to approximately pages read per hour.
According to the trendline, each 0.5-hour increase in the number of focused hours corresponds to a decrease of approximately pages read per hour.

The first question is : The data point for which the distance to the trendline is greatest corresponds to approximately ___________ pages read per hour.
Seeing the graph, we can visually observe the blue dots scattered around the black slope line. The dot which is at a greater distance from the black slope line is : When the number of pages read per hour is 80, and the Number of focussed hours is 7.
Question 2: According to the trendline, each 0.5-hour increase in the number of focused hours corresponds to a decrease of approximately______________ pages read per hour.
The focussed hours increases as 1 hour, while the number of pages read per hour is increased at 20 hours.
When the number of pages read is 140, the number of focussed hour is approximately 2.7
Similarly, when the number of pages read is 160, the number of focussed hour is exactly 2.
The increase in number of focussed hour = (2.7 -2) = 0.7 approx, for the same time period the decrease in number of pages is (1-140)=20
Answer:
80
20

thank you for ur explaination. however i am still struggle to understand 2nd question explained on " The increase in number of focussed hour = (2.7 -2) = 0.7 approx, for the same time period the decrease in number of pages is (1-140)=20 "
is it because 0.7 ~ 0.5h, so u need to identify initially which part has around 0.5h changed in the graph? then u got the 2.7-2?
