For it to be parallel to x = 0, the line must be x = something.
We know that no matter what y equals, x must equal zero. Let's apply that logic to the point, (2,4). It doesn't matter what the y is (in this case 4) but x must equal 2.
So, the equation is x=2. This is vertical, like x=0, but is just two points to the right.
