3. Marsha has two cubes with one number
on each side. Each cube is numbered
from 1 to 6. Marsha rolls both number
cubes at the same time. What is the
probability that the total of the numbers
facing up will equal 12?

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:

but which class are u may know that first

it is 570
