Purple paint is made from mixing red paint and blue paint. The diagram shows the relationship between the amount of red paint and the red paint
amount of blue paint needed to make purple paint.
blue paint
What fraction of each gallon of purple paint is red paint?

5? im not 100% sure tho

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
