Directions: Write the linear equation in Standard Form. y=x−7
Incorrect Answer Given:

x−y−7=0
Why is this incorrect?

Question 1 options:

A)

Answer fails to be in the form:

Ax + By = C

B)

Answer fails to make sure A, B, C are not fractions (or decimals).

C)

Answer fails to make sure A is positive.

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

x + 4/7
