Answer 2

-2x = 8 <---this of it as this and solve for x

Answer 3

-2x<8

divide both side by -2 and because you are dividing the numbers with a negative number, you need to flip the inequality sign. Then it becomes
x>-4
and the graph is the fourth one.
It's an open circle because the inequality sign does not have the half equal sign.
