The graph shows the number of cookies eaten and the number of calories consumed:
A scatter plot is shown with the title cookie stats. The x-axis is labeled cookies eaten, and the y-axis is labeled calories consumed. Data points are located at 1 and 40, 2 and 80, 3 and 120, 4 and 160, 5 and 200, and 6 and 240. A line of best fit connects the points 1 and 40 to 6 and 240.
Which statement best describes the relationship between the number of cookies eaten and the number of calories consumed? (4 points)
No relationship can be determined.
As the number of cookies eaten increases, the calories consumed decreases.
As the number of cookies eaten increases, the calories consumed increases.
As the number of cookies eaten decreases, the calories consumed increases.
As the number of cookies eaten increases, the calories consumed increases.
A scatter plot and a possible line of best fit is shown:
A scatter plot is shown. Data points are located at 2 and 3, 4 and 3, 4 and 5, 6 and 5, 6 and 6, 8 and 7. A line passes through 1 and 1 connecting to 8 and 7.
Is the line of best fit accurate for the data shown? (4 points)
Yes, because it touches the y-axis
Yes, because there are about the same number of points above the line as below it
No, because the line does not touch any points
No, because the line should touch every point
