Y = -2x -8 what is the solution to this problem?

x=−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

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
