How about giving the teacher the benefit of the doubt? Just because you (plural) didn't quite know what a line plot is, doesn't mean the teacher doesn't know. We should assume it's part of the curriculum the teacher is supposed to cover & he/she should be familiar with the terminology. I knew exactly what a line plot looks like as soon as I saw the phrase in the OP. I bet many others who might read this thread would too.
On the other hand, I bet there are as many incompetent teachers out there as there are incompetent (insert an occupation here).
I'm sure the teacher knows exactly what it is, because once I figured it out my daughter knew exactly what I was talking about. And if she meant something different, I believe she would have used the word "graph"
