Justin has 100 feet of fence to make a rectangular dog pen. what dimensions of the rectangle will provide the largest pen for the dog? a. 20 ft by 30 ft b. 25 ft by 25 ft c. 35 ft by 15 ft d. 40 ft by 10 ft

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
