If y is indirectly or inversely proportional to x, with k as the constant of proportionality, then:
y = k
x
The relation is also written as: [tex]y \alpha x ^{-1} [/tex]
Indirect/Inverse proportion means that as the first set of quantity in the relation increases, the corresponding quantity from the second set decreases.
Examples:
1) As the speed (s) increases, the time (t) to reach a destination decreases.
s = k/t
2) As the number of workers (w)to finish a certain job increases, the time (t) (hours, days, etc.) to finish the same job decreases.
w = k/t
