Which expression represents the word phrase six decreased by one third of a number? 13n−6

6−13n

−6−13n

I don't know.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
