Which of the following equations is an example of inverse variation between variables x and y ?


A.) y=15x

B.) y= x-15

C.) y=15/x

D.) y=x/15

Verified Answer :

The option C) y = 15/x

a) y = 15 x is an example of direct variation, with proportionality constant = 15

b) is an example of linear variation (it is the equation of a straight line that does not pass through the origin)

c) y = 15/x => y*x = 15 = constant which is the characteristic of an inverse relation

d) y = x/15 is an example of an inverse relation, with proportion constant = 1/15 

Answer: Y=15\x

Step-by-step explanation:

A
