A contract delivery worker is paid $10.00 per hour as well as $0.60 per mile. Assuming a 40 hour work week, which of the following
equations below gives the amount of money per week that the worker makes before taxes, M, as a function of the number of miles,
m, driven during the week?

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

graph of this function as shown below:

step-by-step explanation:

one set of data has more variation than the other. hope this !
