Imagine you heard the meteorologist on TV announce that the atmospheric pressure for the day is going to be 767 mmhg. You know that 1 atmosphere of pressure = 760 mmhg. So. based on the surface pressure map of the United States that you just created, which region (northern, southern, eastern, western, central) of the country might you be living in where the pressure is 767 mmhg?

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
