What type of graph is used to show counting numbers?

Answer 1

It's tempting to say a line (or possibly an edge) graph, but a line graph has two axes. Graph theory can get "abstractive" real quick. And we don't need all that "clique" stuff, do we? The counting numbers are the integers. They include all the positive integers and all the negative integers and zero. (That's three sets of numbers in the set of integers. And one of the sets, the set with zero in it, has only one member.) Let's try something a little different. We often talk about the real number line as a way to "graph" the integers. Heck, they're all there. So are all the other real numbers, but those counting numbers are still on the real number line. The source of the difficulty here may be that it is "unclear" to ask what type of graph is used to show the counting numbers instead of just saying, "What is used to show the counting numbers?" The answer to that question is usually a simple one. "We use the real number line to show the counting numbers."
