Jenna makes a design of 6 squares for every 4 circles. Staci makes a design of 9 squares
for every 6 circles. Alana makes a design of
15 squares for every 9 circles. Whose ratios
are equivalent?

A: Jenna and Staci only

B: Jenna and Alana only

C: Staci and Alana only

D: All three ratios are equivalent

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
