First, a couple of questions for you:
(1) what can you say about the slopes of two lines that are known to be parallel?
(2) What will the slope of the new line be?  How do you know?
(3) Given the slope of a line and the coordinates of one pt. through which the line passes, into which of the several forms for the eq'n of a straight line would you substitute these values?

Neither of us will be giving you the answer: that accomplishes nothing.  We will help you find it, however.

How do you know if two lines are parallel?  How would you describe a pair of parallel lines?
