A commander wants to arrange his soldiers in such a way that the number of row is equal to the number of columns. If the total number of soldiers is 2800, find how many soldiers would be left out in this arrangement? Also, find the number of rows in the arrangement.

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
