Joel is using the two data points closest to the line to determine the equation of the regression line. What should Joel find for the slope of the line? Round to three decimal places.
slope=rise/run we see that the slope will be negative it is more accurate the farther we are apart we wiill use the points closest to the line, those are (3.5,3.5) and (5,1)
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1) for this one (1-3.5)/(5-3.5)=-2.5/1.5=-1.666666666≈-1.67
