Answer:
It think your answer is M
Explanation:
Ok, it says what line is parrallel to "J", I would get a peice of paper and try to draw it out. Not the whole thing, just the lines. And I would take the lines J and M and keep drawing them longer and longer. If they both end up running into eachother then they are not parrallel. But if they keep there distance then M is your answer. I would try that with all the lines.
Hope this helps :) Have a great day!
