The scatter plot below shows the relationship between the weekly hours of watching television and the weekly hours spent exercis
ing, by the students of a high school: A scatter plot is shown with the title Leisure Activities. The x-axis is labeled hours spent exercising, and the y-axis is labeled hours spent watching TV. Data points are located at 1 and 4, 2 and 6, 2 and 3, 4 and 3, 6 and 1, 4 and 5, 7 and 2, 0 and 6. A line connects the points 0 comma 6 and 8 comma 0.
What is the y-intercept of the line of best fit, and what does it represent?
6 hours; the number of hours students exercise when they do not watch television
6 hours; the number of hours students watch television when they do not exercise
8 hours; the number of hours students exercise when they do not watch television
8 hours; the number of hours students watch television when they do not exercise
Answer: 6 hours; the number of hours students watch television when they do not exercise
Step-by-step explanation:
Given: The x-axis is labeled hours spent exercising, and the y-axis is labeled hours spent watching TV .
From the given scatter plot and with repect to the given optionsa , a data point is located at x=0 and y=6, which represents the y intercept of the line of best fit.
Here 6 represents 6 hours; the number of hours students watch television when they do not exercise. [since x=0]
