What is 15 over 8 as a mixed number

1 and 7/15

Step-by-step explanation:

8 goes into 15 without going over just 1 time.  You have 1 whole.

8x1 = 1

15-8 = 7 ->   you have 7 left, that you must divide by 15

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
