Ermal Is a project manager for a new housing development. He is in charge of making sure that 400 residences are completed soundly and on time. What skill would be useful to Ermal in his career?

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:

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
