Is -7 , -6 a solution for y=2x-8

x=-y/2−4

Explanation:

Rewrite the equation as −2x−8=y.

−2x−8=y

Add 8 to both sides of the equation.

−2x=y+8

Divide each term by −2 and simplify.

x=−y/2−4

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
