$m = -1/3$

The formula for the slope of a line based upon two coordinate points is

$m = (y_2-y_1)/(x_2-x_1)$

For the coordinate points $(1,-2) and (-2,-1)$
$x_1 = 1$
$x_2 = -2$
$y_1 = -2$
$y_2 = -1$

$m = (-1-(-2))/(-2-1)$

$m = 1/-3$

The slope is

$m = -1/3$

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