Predicting a y value for a given x value can be calculated when given the regression equation.
$$ y = mx + b $$
Where $y$ is the predicted value, $m$ is the slope, $x$ is the given value and the $b$ is the intercept.
$$ intercept = \bar{y} - $$
$$ intercept = \bar{y} - slope*\bar{x} $$
$$ slope = \frac{r * \sigma_y}{\sigma_x} $$
