x/y type of question

I though is two numbers ar ethe same the result is alsways 1...

If both X and Y are nonzero numbers what is the value of x/y?
1) x=6
2) y^2=y^2

why is E?
:shock:

first of all I think you mean x^2 = y^2 (1). Now since we have squares
we have 2 cases for example (-3)^2 = (3)^2 and equation (1) holds
for y=+,- x and not just for positive x only, so ratio could be either 1 or -1
