How do you find the slope given (-4,-1) and (1,-2)?

1 Answer

The change in y divided by the change in x

Explanation:

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

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

Slope = $\frac{- 1 - (- 2)}{- 4 - 1}$ ${ -1 - (-2)}/( -4-1)$ This gives

Slope = $\frac{1}{- 5} = - \frac{1}{5}$ $1/(-5) = - 1/5$
