This is pretty much the same question I just answered...
So imagine this is a number line...
O----------------------------------------------------------------O

-10 -5 0 [tex]\frac{1}{2}[/tex] 3 10
[tex]\frac{1}{2}[/tex] is half of 1, so that should be the correct way on plotting the 3 points.
Hope this helped!
