2/-3 divided by ( -1 2/7 )

14 / 27

Step-by-step explanation:

(-1 2/7) is just the sneaky weird way of saying (-1 - 2/7) = (-9/7)

now, (2/-3) / (-9/7) = 2 * 7 / -3 * -9 = 14 / 27

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
