My post has been closed/put on hold, but I don't know how to make it better

I have a question about my Mathematics Stack Exchange post: How can I draw a 10 unit long line?

So, as you can see, it's on hold/closed, and if you look at the comments I asked why it's unclear but didn't get a reply.

I don't know how it's unclear, or what can be done to make it clearer. Surely if people were able to answer it, then it's clear?

Is it the redundancy that is bad? ("<stuff with x> that uses only x")

If it's not the redundancy, is it the question's length? It's a quite short question but I'd think that's still fine?

Did I tag it wrong? Should I not have mentioned plotting at all?

• It will very often happen that because the problem is clear to you, you assume it will be equally clear to your Readers. In a Comment there you wrote that "To put it simple, I wanna describe $0<=x<=10$ with an equation." As you seem to know, that is a (pair of) inequalities, and it's unclear why you expect (or want) to replace them with an equation. A start might be to edit your Question to express the problem in terms similar to your "simple" Comment. – hardmath Sep 30 '16 at 11:18
