I should get $y=-11$

Explanation:

In this cas you are lucky...your original line is perfectly horizontal (slope $=0$ )!!!
So, to be parallel you need another horizontal line that passes through $-11$ i.e.:
$y=-11$

In general you can write the equation of a line as:
$y=mx+c$
where:
$m=$ slope
$c=$ y-intercept
so here you need:
slope $=m=0$
y-intercept $=c=-11$
