12 points, not 10!
As answer 1 and 2 are correct, only two points, not 12?
The "empty circle" means that the graph approaches but DOES NOT REACH that number. Thus this device is used to graph equations where the < and > signs are used.
x > 5 a circle around 5, a line to the right of 5 with an arrow on the RH end of the line.

If it is greater than or equal - less than or equal to then you fill in the circle ... if it is simply greater than or less than, than you leave the circle unfilled (or hollow).
