Charmaine spent $22 on fruit at the grocery store. She spent a total of $55 at the store. What percentage of the total did she spend on fruit?

the answer to the question is a  

it has the same slope and the same y-intercept.

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
