The correct answer for this question is this one:
I'd not sure if im approaching this right, but i'd say the 4th graph. I'm going with that using substitution. If y=1 then you get 7/3. Then if y=2 you get 7/9. And after that point it keeps getting smaller and smaller but it will never touch or go pass 0, just keeps getting closer.
Hope this helps answer your question and have a nice day ahead.
