Question

Which equation represents a proportional relationship that has a constant of proportionality equal to One-fifth?

y = x minus one-fifth

y = x + one-fifth

y = one-fifth x

y = 5 x

Answer 1

Explanation:

Option (c) y=1/5x

Answer 2

Option C)

`y = (1)/(5)x`

Explanation:

We are given the following in the question:

`y \propto x`

Removing the sign of proportionality and introducing the constant of proportionality, we have

`y = kx`

where k is constant of proportionality.

We are given

`k = (1)/(5)`

Putting value, we get,

`y = (1)/(5)x = (x)/(5)`

Thus, the equation representing the relationship is

Option C)

`y = (1)/(5)x`
