How do I find the equations of 2 parallel lines 2 units away from a given line?

When you have a line's equation, and are asked to find the equations of the 2 parallel lines to it, which are 2 units away...where do I start?

Do you know what the slope and y-intercept (!) represent?

Hey its grand I solved it. It was just solving a quadratic from the perpendicular distance formula. My absolute value signs threw me off!

Thanks anyway!
