Solve the following system of equations by graphing. y = –½x – 1

y = ¼x – 4
Question 13 options:

A)

(4,–3)

B)

(–4,3)

C)

(–3,4)

D)

(3,4)

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
