Solve for g. g + (-5) = 27g =

Solve for g:

g + (-5) = 27

Operate the parentheses:

g - 5 = 27

Adding 5 on both sides of the equation:

g = 27 + 5

g = 32

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
