The graph shown below shows the relationship between the age of drivers and the number of car accidents per. It is unlikely that there wouldn't be any correlation at all, but it would be very weak for sure, so the correlation coefficient would tend towards zero, and thereby the slope of the regression line would also be close to zero. Notice how the residuals become much more spread out as the fitted values get larger. a.) One common transformation is to simply take the log of the dependent variable.
