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

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
