A storage tank shown at the right is to be painted what is the area of the surface to be painted assume that the bottom does not need painting round to the nearest whole number. PLEASE HELP I DONT UNDERSTAND!

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
