For this case we have that by definition, the slope of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

Where:

$(x_ {1}, y_ {1})$ and
$(x_ {2}, y_ {2})$ are two points through which the line passes.

According to the figure we have to, the line goes through:

$(x_ {1}, y_ {1}) :( 0, -2)\\(x_ {2}, y_ {2}): (- 2,0)$

Substituting we have:

$m = \frac {0 - (- 2)} {- 2-0} = \frac {0 + 2} {- 2} = \frac {2} {- 2} = - 1$

Thus, the slope of the line is -1.
