in scatterplot I ,the points fan out as X increases, so this scatterplot goes with residual plot D
in scatterplot II,the points are scatter more,, so this scatterplot goes with residual plot A
in scatterplot III ,the points show curvature, so this scatterplot goes with residual plot B
in scatterplot IV ,the points closed to regression line, so this scatterplot goes with residual plot C

Not all bivariate relationships are linear. When you plot a scatterplot, sometimes you observe a curved relationship. In those cases, we can apply a transformation to the data that will make the relationship approximately linear. [We generally prefer simpler models. And linear regression models are simpler than curved regression models. Also, transforming data is common in statistical practice.] One of the most common transformation methods is the log transformation. In this problem, you apply the log transformation to both variables...
