What is the equation for the linear model in the scatter plot obtained by choosing the two points closest to the line?

Coordinate grid with scatter plot and arrow showing Variable x on horizontal x-axis and Variable y on vertical y-axis. Below the graph is a frequency distribution table showing data for Variable x and Variable y.

y=−3x+57.5

y=3.5x+57.5

y=−3.5x+32.5

y=−3.5x+57.5

Step-by-step explanation:

The picture of the question in the attached figure

step 1

take the two points closest to the line in the graph

(5,40) and (15,5)

find the slope

The formula to calculate the slope between two points is equal to

substitute

step 2

Find the equation of the line in slope intercept form

we have

substitute and solve for b

substitute

b) the dogs need to shift their focus to human scent.

the answer is $42.96
