Original Math

 * $$\hat\beta = \frac {n \sum x_iy_i - \sum x_i \sum y_i} {\Delta}

=\frac{\sum(x_i-\bar{x})(y_i-\bar{y})}{\sum(x_i-\bar{x})^2} \,$$


 * $$\hat\alpha = \frac {\sum x_i^2 \sum y_i - \sum x_i \sum x_iy_i} {\Delta}= \bar y-\bar x \hat\beta $$

Versions without means
Slope:
 * $$m = \frac {n \sum xy - \sum x \sum y} {n \sum x^2 - (\sum x)^2}

\,$$

Intercept:
 * $$b = \frac {\sum y - m \sum x} {n} $$

Equation of Line:
 * $$y = mx + b \, $$
