Answer:
<em>The correct option is: A. X= -4</em>
Step-by-step explanation:
The equation of the given line is: 
As the given line is a <u>vertical line parallel to y-axis, that means the slope of the line is 'undefined'</u> or
, where
is any real number.
Now, the slope of the line which is parallel to the given line will be also
, as <u>the slopes of parallel lines are always equal</u>.
The parallel line is passing through the point (-4, 1). So, using point-slope form.......

Thus, the equation of the parallel line will be:
