The last answer would be correct because a closed cicle on a number line is less than/greater than or equal to and an open circle is less than or greater than. Because you are going to the left, into negatives, your answer would be d.
We know that its gonna be one of the ones with the line underneath because it has a closed circle (which means filled in). And we know that its going to be a ≤ 9 because my teacher taught me a trick. Whichever way the arrow or pointy side of the sign is facing that's the way the arrow is going to be facing.
