  1.25 pages per minute

Step-by-step explanation:

To find pages per minute, divide pages by minutes:

  (50 pages)/(40 minutes) = (50/40) pages/minute

  = 1.25 pages/minute

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
