There is not enough information to answer this problem.

Step-by-step explanation:

A proportional function means that if you change X, Y will change in the same proportion.  And that proportion of change will remain the same no matter which two values of X you take to compare them.  

But that proportion will vary from function to function.

Without knowing what the function is, it's impossible to know the value of Y for a given X... it could be anything.

which expression represents the approximate length of bc?

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
