It looks like you're referencing the formula for the slope $b_1$ in the context of linear regression:

$b_1 = r \cdot \frac{s_y}{s_x}$

Where:

• $b_1$ is the slope of the regression line.
• $r$ is the correlation coefficient.
• $s_y$ is the standard deviation of the $y$-values.
• $s_x$ is the standard deviation of the $x$-values.

To find the slope $b_1$, you'll need the following information:

1. The correlation coefficient $r$.
2. The standard deviation of $y$ ($s_y$).
3. The standard deviation of $x$ ($s_x$).

If you already have these values, simply plug them into the formula.

Would you like to provide the values for $r$, $s_y$, and $s_x$ to calculate the slope? Or do you need help with how to calculate them?
