The scatterplot displays the number of pretzels students could grab with their dominant hand and their handspan,
measured in centimeters. An analysis was completed
and the computer output is shown.
Using the computer output, what is the equation of the
least-squares regression line?
0 7 = 4.317 + 0.310x
0 $ = 0.310 + 4.317x
0 7 = 14.71 + 1.585x
O y = 1.585 - 14.71x
