Answer:

D

Step-by-step explanation:

We can create a number line like this:

9th avenues -------5stops-------Grand Street--------6stops------125th Street

Since we know that 125th Street Station is at 0, we can clearly see that 9th avenues is (6+5=11) 11 units to the LEFT of 125th Street Station. That would be 11 units to the left of 0, which is -11 on the number line.

Thus, 9th avenue station would represent -11 on the number line.

D is the correct choice.
