This is a double replacement precipitation reaction.

See How can the reaction KBr + AgNO3 -> AgBr + KNO3 be classified?

Your equation is

KBr(aq) + AgNO₃(aq) → AgBr(s) + KNO₃(aq)

Two soluble ionic compounds, KBr and AgNO₃, have reacted to form the insoluble compound, AgBr.

The metal ions K⁺ and Ag⁺ have exchanged partners, so this is a double replacement reaction.

Also, two soluble reactants have formed an insoluble product, so this is a precipitation reaction.

The AgBr appears as a creamy white precipitate.
