Since the signal of the inequality is "greater than", so the value -2 is not part of the solution, because -2 is not greater than -2.
Therefore the circle will be open.
The solution is all values of r smaller than -2. That means the values to the left of -2.
So the arrow will point left.
The solution is the values smaller than -2, to the solution set start with a circle in the value -2.
