Mara decides to plot her neighborhood on a coordinate plane. She plots her house at the point (0,0), her school is located at (0,8), the library at (3,8), and the softball field is at (3,0). One day she decides that after school she will run by the library to grab a book, and then head to softball practice and then back home. How far on the coordinate plane does she travel starting at home that morning? Leave your answer in units.

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:

the answer is 99.
