No its not a good reasonable fit to use a linear regression line. Why not? Because r = 0.15 is closer to r = 0 than it is to r = 1. This is fairly weak linear correlation. If r was say something like r = 0.7 or higher, then it would be stronger linear correlation.

<em> </em>

<em>The correlation coefficient measures how well a line fits a set of data. </em>

<em> </em>

<em>The correlation coefficient suggests that the relationship between the two variables is weak. </em>
