A dietitian believes that eating more leafy green vegetables lowers blood pressure. She asks a group of you and your friends to continue eating as you normally do. She asks your brother and his friends to add two servings of spinach to
their daily diet. She records the blood pressure levels of all subjects before and after the diet change. Which group of an
experiment are you part of?
-single-blind
-confounding
-control
-experimental

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
