For the first one there should be a dot on -3 and the arrow moving to the right(------>) and it should be an open circle.
Hint ( If the symbol is greater than or less than it is an open circle. If the symbol is greater than or equal to or less than or equal to it is a closed circle.)
For the second one there should be a dot on 1 and the arrow moving to the left(<-----) and it should be a closed circle.
And so on for the rest.
But remember if the arrow is ( > ) it goes to the right and if the arrow is ( < ) it goes to the left.
Hope this really helped you.
