Answer 2

A = P r (1+r)^n / [ (1+r)^n -1]
where

A = payment Amount per period
P = initial Principal (loan amount)
r = interest rate per period
n = total number of payments or periods
here n = 24 months
r = .09/12 = 0.0075
(1+r) ^24 = (1.0075)^24 = 1.1964
so
10,000 (.0075)1.1964 / [ .1964]
= 456.87
