The formula is $$r = b_1 \frac{s_x}{s_y},$$ where $r$ is the correlation, $b_1$ is the incline, and also $s_x$ and also $s_y$ are the typical inconsistencies of the independent $(x)$ and also reliant $(y)$ variables, specifically.

A reference is Wikipedia is web page on simple linear regression. See the formula for $\hat{\beta}$.
