Question

Adam has the scatterplot shown for his data set, where snowfall is measured in inches, and he is trying to describe the line of best fit. Which choice correctly describes the line of best fit? A) As the amount of snow decreases, the number of accidents decreases. B) As the amount of snow decreases, the number of accidents increases. C) As the amount of snow increases, the number of accidents increases. D) There is no relationship between snowfall and the number of accidents.

Answer 1

C) As the amount of snow increases, the number of accidents increases.

Explanation:

There is a relationship between snowfall and accidents since it creates a linear line. Since the line of best fit has a positive slope you know that both snowfall and accidents must be increasing.

Answer 2

C) As the amount of snow increases, the number of accidents increases.

Explanation:

An image showing the scatter plot is attached.

From the attached imaged, the scatter plot is a straight line which goes up along the X - Y axis.

X = snowfall

Y = accident

Since the scatter plot is going up increasingly for any value plotted; it means as the amount of snow increases, the number of accidents increases. That is, as X (snowfall) increases Y (accident) increases also.
