James paid $15 for a pizza on his way home from work on Friday night. Unfortunately, this purchase put him over the limit on his credit card and he was charged a $35 over the
limit fee. How much did the pizza actually cost him?

step-by-step explanation:

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

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
