$y = - 1$
If the line is parallel to $y = - 4$, then it also must be of the form $y = a$. This is because only equations of the form $y = a$ are vertical lines.
Now, if the line passes through $\left(- 2 , - 1\right)$, then, in our equation $y = a$, $y = - 1 \mathmr{if} x = - 2$. Substituting these values in, we get $a = - 1$.
Our final answer is $y = - 1$.
