Find the equation of the regression line.
Construct a scatter plot of the data and draw the regression line. Plot the x-values on the horizontal axis and they-values on the vertical axis.
Construct a residual plot. Plot the x-values on the horizontal axis and the residuals on the vertical axis.
Determine if there are any patterns in the residual plot and explain what they suggest about the relationship between the variables. ( The residual plot shows/does not show a pattern because the residuals fluctuate/do not fluctuate about 0. This implies the regression line is/is not a good representation of the relationship between the variables.
