$m = - \frac{2}{3}$ $m=-2/3$

$x_{1} = 4$ $x_1=4$
$y_{1} = 6$ $y_1=6$
$x_{2} = 1$ $x_2=1$
$y_{2} = 8$ $y_2=8$

Slope $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $m=(y_2-y_1)/(x_2-x_1)$

$m = \frac{8 - 6}{1 - 4} = \frac{2}{- 3} = - \frac{2}{3}$ $m=(8-6)/(1-4)=2/(-3)=-2/3$

What is the slope of the line passing through the following points: (4,6) , (1,8) (4,6),(1,8)(4,6) , (1,8) ?
