(a) Find the equation of the regression line for the given data, letting Row 1 represent the x-values and Row 2 the y-values. Sketch a scatter plot of the data and draw the regression line.
Input the values of the slope and intercept for the regression line when Row 1 represents the x-values.
V = - 3.906 x + ( 96.969)
(Round to three decimal places as needed.)
Construct a scatter plot of the data and draw the regression line. Plot Row 1 on the horizontal axis and Row 2 on the vertical axis. Choose the correct graph below.
