Double Polomar. It's a 100% strength knot, so it will not slip or break at the knot. You can find instructions on how to do it I'll edit a site in if I find it. You make a look in your line, pass it through the eye, pass it through again, tie a sqaure knot, pass the hook through the loop, wet and pull tight, I'll look for better instructions.
Edit for link
Power Pro knot
Also, in the future, the search function is a great way to find general info like this!
