Joe shine polishes shoes for a living at the airport. he has determined that he can use the equation p=-35+5n to calculate his profit. what do you think he could be a possible real world meaning for the number -35?

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:

70,000 + 6,000 + 800 + 30
