Russo is trying to find the area of the lake in his neighborhood. He sees a duck at point C and uses a tape measuring application on his phone to find that the duck is 16 feet from the point of tangency (point B) to the lake, and the point of tangency is 12 feet from the fountain in the center of the lake (point A).

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
