Question

a proportional relationship is represented by the equation 2x=18y . If y=x , where k is the constant of proportionality, then what is the value of k.

Answer 1

Answer:
`\bold{k=(1)/(9)}`

Explanation:

The constant of proportionality is y = kx. Solve the given equation for "y" to find k-value in front of "x".

18y = 2x

`(18y)/(18)=(2x)/(18)`

`y=(1)/(9)x`

`k=(1)/(9)`
