in air, the sound of speed, S, in meters per second, is a linear function of the air temperature T, in degrees celcius, and is given by S(T)=0.6T+331.4. which of the following statements is the best interpretation of the number 331.4 in this context?

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

to be honest i don't know but i need points so
