Question

Which equation represents a proportional relationship that has a constant of proportionality equal to mc003-1.jpg?

Y/X= 7/10

Y/X= 1/7

XY= 7/10

XY= 1/7

Answer 1

A) y/x= 7/10. just took the quiz on e2020

Answer 2

we have that

The constant of proportionality k is equal to
`(7)/(10)`

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
`(y)/(x)=k` or
`y=kx`

so

substitute the value of k in the formula

`(y)/(x)=(7)/(10)`

therefore

the answer is

`(y)/(x)=(7)/(10)`
