 No worries; if you did, I got over it.

 1/x goes to 0 as x tends toward infinity. 
 y/0 is undefined for all y. 
(Except sometimes using L'Hopital's rule) 
 
It's ambiguous use of language to say that anything can equal infinity.  Infinity is not, strictly speaking, a number. It is a concept of unendingness.  There are some uses of infinity as a number, e.g. in infinite sums, and some other cases, but those are usually additionally defined or constrained infinities which a textbook glazes over in one passing phrase.  Usually, that phrase involves the word convergence.
