x = 0 is a vertical line through the x-axis at the origin. it has an undefined slope so you cannot use the point-slope formula here.
A line parallel to it will also be a vertical line. If the line goes through (-5,2), it is going through the x-coordinate of -5 at an infinite number of y-coordinates, so x = -5 is the equation of that line.
