Which of the following expressions show inverse proportionality? y =kx x =ky y=x/k y=k/x

Respuesta :

Two values are said to be inversely proportional when the value of one increases, the other decreases. Hence inverse proportionality is expressed in a fraction

y∝[tex] \frac{1}{x} [/tex]

as the value of x increases, the value of y will decrease

This is expressed as an equation using the inverse proportionality constant k

y= k. [tex] \frac{1}{x} [/tex]

or

y=[tex] \frac{k}{x} [/tex]

Hence the fourth option is the correct answer
