Which shows how to use place value and the distributive property to find 12(57)?
a) 12(5)+12(7)
b) 12(50)+12(7)
c) 10(2)+50(7)
d) 10(50)+2(7)

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:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
