Subtract . −1/3−1 2/3 -1/3 is a fraction) 1 2/3 is a fraction) give explanation, how you solved this, and the answer no guesses!

Change 1 2/3 to 5/3 because it is easier to add and subtract fraction when they are  improper. This makes -1/3-5/3, -1-5=-6, so the equation equals -6/3 which simplifies to -2.

answer: 25 is the correct answer

step-by-step explanation:

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
