since y=-9 is a horizontal line, so must our line be horizontal and that means m=0
%0D%0Ay-y%5B0%5D+=+m%28x-x%5B0%5D%29%0D%0A
becomes
%0D%0Ay-%28-5%29+=+0%28x-%28-3%29%29%0D%0A
and so
y=-5

One standard equation for a line is y=mx%2Bb where m is the slope and b is the y-intercept.
through (-3,+-5);
line y=+-9, compared to y=mx%2Bb, you can see that slope is 0 and
y-intercept b=-9
if lines parallel, they have same slope; so, the line parallel to y=+-9
will be a line y=-5
