The question is more for mathematic thrillers. as u know if two lines are perpendicular the product of there?

slope is (-1). Now if we take X-axis & Y-axis slope of X-axis is 0 and that of Y-axis is infinity or is say indeterminant then product of these slope is also indeterminant. then how can u say that they are perpendicular. Don't tell me to measure the angle. i want to know why is that contradiction is here. i hope i was able to express my self.

Solubility/Reactions?

I add aqueous AgNO3 to NaOH and a precipitate forms. Then I add nitric acid HNO3 and the precipitate dissolves. How would I write the equation for my reactions. Would this be correct?

AgNO3 (aq) + NaOH (aq) --> AgOH (s) + Na+(aq)

And then...
AgOH (s) + Na (aq) + HNO3 (aq) --> AgNO3 (aq) + H2O (l) or would it instead yield Ag(NH3)2 (aq)??
