Question

Question : Elaina is using the two data points closest to the line to determine the equation of the regression line. What should Elaina find for the slope of the line ? Round to three decimal places

Answer 1

we will use the following coordinates (4,4) and (5.5,3.5) these two are closest to the line.

Then we will do the following to find the gradient (slope)
(3.5-4)/(5.5-4) = - 1/3
rounded to 3 decimal places would give us -0.333
