Question

This scatter plot shows the association between the fat content and the calorie counts of some food items. Which equation represents the line of best fit?

Answer 1

Looking at this, it seems like B would be your answer. 

Answer 2

Hence, the equation that represents the line of best fit is:

`y=(160)/(7)* x+100`

Hence, option: B is correct.

Explanation:

We are given a linear correlation association between x and y as the line of best fit is a straight line.

Also it depicts a positive relationship between x and y since the points are increasing with increasing value of x.

Now the equation of line that best represents the line of best-fit of the scatter plot i.e. which gives a best estimate of the data in the scatter plot is:

`y=(160)/(7)* x+100`

Hence, option: B is correct.
