This graph is called the x graph.
The lines above represent nothing other than invisibility!
One way of doing it would be do put smaller tick marks in between the larger tick marks for whole numbers. So if you want to represent, 1, then 1.25, 1.50, 1.75 then 2 on a number line, you could put a large tick mark with the number '1' above it, then 3 evenly space smaller tick marks, then another large tick mark with the number '2' above it. If you have enough room, you could write the decimal numbers above the smaller tick marks, too.
The number 3 in this decimal above is in the thousandth's place, hence it is supposed to represent 3/1000th's in the number above. Does that answer your question? If it doesn't I can explain more in detail/ more simplified so you understand it better. I really want you to learn and understand things well!
The radical symbol ( √ ) followed by a line above what's in the radical, designates positive square root.
