The slope:
$m = \frac{- 3}{4}$ $color(blue)(m = (-3)/(4)$

$(8, - 1) = x_{1}, y_{1}$ $(8,-1) = color(blue)(x_1,y_1$

$(4, 2) = x_{2}, y_{2}$ $(4,2) = color(blue)(x_2,y_2$

The slope can be found using formula:

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

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

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

$m = \frac{3}{- 4}$ $m = (3)/(-4)$

The slope:
$m = \frac{- 3}{4}$ $color(blue)(m = (-3)/(4)$

What is the slope of the line passing through the following points: (8, -1) , (4, 2)(8,−1),(4,2) (8, -1) , (4, 2)?
