#x=-2#

Explanation:

#x=4# is a vertical line; so any line parallel to it must be a parallel line; that is it must be of the form #x=c# for some constant #c#

If the required line goes through #(x,y)=(-2,-7)# then #x=-2# at that point and therefore must be equal to #-2# for all points (to be a vertical line).
