Frank bought lunch for $5.60 at a diner. he spent two dollars to ride the bus to the mall and back, and spent $6.50 while he was at the mall. his friend bill paid him back five dollars that he had borrowed last week. if frank arrived at home with $10.50 in his pocket how much did he have one he left home that morning?

based on context clues you gave i'm assuming the answer would be c.

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
