Well first of all you know that the closed dot is inclusive of the value -1, so your answer choice must have a $$\le or \ge$$
then all you have to do is solve for y and figure out which one includes all the values on the line

why would it only be $$\le or \ge $$ for number -1?

anonymous · Answer

the closed dot on the number line means it includes the number that it is on (an open dot would mean it doesn't) and > or < do not include the number so they cannot be the answer.

And it has to be -1 cause that's the endpoint of the line
