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

Explanation:

Step1: Analyze the slope of the line of best fit

The equation of the line of best fit is \(y = - 7.7547x+5.44496\). The slope \(m=-7.7547\lt0\).

Step2: Determine the relationship

Since the slope is negative, as \(x\) (snowfall) increases, \(y\) (number of accidents) decreases.

Answer:

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