$m = - \frac{5}{3}$ $m=-5/3$

determine the slope:

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

$(x_{2}, y_{2}) = (- 2, - 6)$ $(color(red)(x_2),color(red)(y_2))=(-2,-6)$

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

$m = \frac{- 6 - (- 1)}{- 2 - 1} = - \frac{5}{3}$ $color(green)m =(color(red)(-6)-color(blue)((-1)))/(color(red)(-2)-color(blue)(1))=-5/3$

What is the slope of the line passing through (1,-1); (-2,-6)(1,−1);(−2,−6)(1,-1); (-2,-6)?
