Need help with this problemThis is what it says: Write the equation for the lines which are at a distance of 3 units from the line x-5y+10=0 I don't get it at all. Help?

By "3 units away" you mean the distance when the lines are parallel? If that's so it shouldn't be too hard, you just have to know some of this: trig functions
