tell how you could use a number line to determine which of two numbers is greater.

Line up the numbers and see which one has the highest number in the leftmost column. If both numbers are the same there, proceed to the next column to the right until a difference exists.
I don't know what you mean by a "number line". You should be able to tell which number of a pair is greater by just looking at them.
