Al made a tree house last summer. He started by making a model. The model included a window with a height of 1/3 inch
and a width 1/6 of inch. The actual window had a height of 1/2 yard and a
width of 1/4 yard. Was Al's model an accurate representation? Explain.

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
