In a line parallel to y-axis, the x would have to be constant, if it's not constant (always the same) then it won't be parallel. Constant values of y could be y=1, y=2... etc, and we have this as an option: y=5, this is the correct answer.

(1) would be parallel to x axis and 2 and 4 are diagonal or sloping lines.
