The scatter plot shows the number of stamps katie collected in different months: . plot ordered pairs 1, 30 and 2, 70 and 3, 110 and 4, 150 and 5, 190. what is the approximate predicted number of stamps she collected in the 25th month? . a. 980. b.990. c.1000. d.1010

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
