The slope is 9.

This is the equation we're going to use:

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

Let's do some simple substitution and solve:

$\frac{1 - - 7}{- 1 - - 2} = \frac{1 + 7}{- 1 + 2} = \frac{8}{1} = 8$ $(1--7)/(-1--2)=(1+7)/(-1+2)=8/1=8$

What is the slope of the line passing through the following points: (-2,-7),(-1, 1) (−2,−7),(−1,1)(-2,-7),(-1, 1) ?
