Why do the reactants NaI(sodium iodide) and AgNO3(silver nitrate) indicate the reaction of Double Displacement?

Explanations:- If a reaction looks like,
AB+CD\rightarrow AD+CB then it is called double displacement reaction as two ions are exchanged in this reaction.

When sodium iodide and silver nitrate are added then a double displacement reaction takes place where iodide ion goes from sodium to solver and nitrate ion from silver to sodium. A precipitate of silver iodide forms in this reaction.


NaI(aq)+AgNO_3(aq)\rightarrow NaNO_3(aq)+AgI(s)
