Slope $m = - \frac{7}{10}$ $m=-7/10$

Given -

$x_{1} = 2$ $x_1=2$
$y_{1} = 8$ $y_1=8$
$x_{2} = 12$ $x_2=12$
$y_{2} = 1$ $y_2=1$

Slope

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{1 - 8}{12 - 2} = \frac{- 7}{10}$ $m=(y_2-y_1)/(x_2-x_1)=(1-8)/(12-2)=(-7)/10$

What is the slope of the line passing through the following points: (2,8) , (12, 1)(2,8),(12,1) (2,8) , (12, 1)?
