Slope: $m = 0$ $m=0$

Explanation:

Slope is defined as the change in $y$ $y$ divided by a corresponding change in $x$ $x$ .

Given two points $(x_{1}, y_{1})$ $(x_1,y_1)$ and $(x_{2}, y_{2})$ $(x_2,y_2)$
the change is $y$ $y$ is $Delta y = (y_2-y_1)$
and the corresponding change in $x$ is $Delta x = (x_2-x_1)$

For the specific points $(-9,-1)$ and $(-2,-1)$
we can see that the slope $m$ is
$color(white)("XXX")(Delta y)/(Delta x) = ((-1)-(-1))/((-2)-(-9)) =0/7=0$
