Question

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

Help Please! Will give medal and fan!,

Answer 1

When the representation of the variables in an equation is similar and has same constants, it is called an inverse equation. An example of inverse equation is y = k/x. This can also be represented as x = k/y. So from the options C is the correct option. y = 15/x which is also x = 15/y
