Put them both into the standard form
which looks like:
+ax+%2B+by+=+c+
---------------
+y+-+4+=+3x+
Subtract +y+ from both sides
+-4+=+3x+-+y+
Write it the other way around
+3x+-+y+=+-4+
---------------
+2y-6x=8+
Just write it this way:
+-6x+%2B+2y+=+8+
Now divide both sides by +2+
+-3x+%2B+y+=+4+
Multiply both sides by +-1+
+3x+-+y+=+-4+
---------------
They are both the same equation, so neither is the
correct choice

        The response in the post by @lynnlo is incorrect.
        I came to bring a correct solution. 


Write equations for both lines in the form y = ax + b.


For the first line, this equation is  y = 3x + 4.


For the second line, this equation is y = 3x + 4.


Now you see that the equations for both lines are identical, so, the lines coincide.


They are neither parallel nor perpendicular.    <<<---===  ANSWER
