Vance graphed the relation between fund-raising profits for the chess club and the number of members. Which equation represents a line that fits the data?

a. y=30n + 160
b. y = = 60n + 160
C. y = 160n + 30
d. y = 160n + 60

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

answer: 2530

hope this
