The value of z varies inversely with the value of w. The constant of variation is [image 1] . Which are possible values for z and w? Check all that apply. z = [image 2] , w = [image 3] z = 2, w = 3z = [image 4] , w = 2z = [image 5] , w = [image 6] z = [image 7] , w = [image 4]

Question illustration
A
z = [image 1] , w = [image 2]
B
z = 2, w = 3
C
z = , w = 2
D
z = [image 1] , w = [image 2]
E
z = [image 1] , w = [image 2]

Joe plotted the points (2, 0.5), (1, 1), and (0.5, 2), and claimed that these points represent an inverse variation relationship. Which statement supports his claim?

A
xy = 1 for all points.
B
xy = for all points.
C
The graph of these points will be linear.
D
Inverse variation states that as one quantity increases, the other quantity also increases.
