I'll do the first one, and leave the other one for another tutor.

If a line's equation is x = a, it is vertical and goes through (a,0) on the 
x-axis.
If a line's equation is y = b, it is horizontal and goes through (0,b) on the
y-axis.
If a vertical line passes through (a,b), its equation is x = a,
If a horizontal line passes through (a,b), its equation is y = b

The given line is in black below. Since the given line's equation is x = -13,
it is vertical and goes through (-13,0) on the x-axis.



The line you want the equation of is the green line, and since it is horizontal
and goes through (-5,-4), its equation is y = -4.
