Answer
(answers vary)
Three additional points on the line:
$(-1, -5)$
$(0, -7)$
$(1, -9)$
Work Step by Step
RECALL:
The slope $m$ is equal to $\dfrac{\text{rise}}{\text{run}}$, and can be interpreted as the average increase in $y$ for every one unit increase in $x$.
A slope of $-2$ means that for every increase of 1 unit in the value of $x$, the value of $y$ decreases by $2$ units.
Thus, to find other points on the same line as the point $(-2, -3)$ just add $1$ to the value of $x$ and subtract $2$ from the value of $y$ to obtain:
$(-2+1, -3-2) = (-1, -5)$
$(-1+1, -5-2) = (0, -7)$
$(0+1, -7-2) = (1, -9)$
Plot the points and connect them using a line.
