The following is the recipe to make one dozen muffins: 1 cups flour; 2 cups sugar; 2 tsps. baking powder; 1 egg; 1 cup crisco; 1 cup skim milk; 1 cup blueberries. if ron regis wants to make 18 muffins, how much of each ingredient will be required for the recipe? (remember, you can split an egg in half)

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

graph of this function as shown below:

you just switch the numbers basically so it would be 3/17
