Does the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the table.
x
2
4
8
12
y
4
2
mc0191.jpg
2/3
direct variation; y = 8/x
direct variation; y = 8x
inverse variation; xy = 8
inverse variation; y/x = 8

Best ResponseYou've already chosen the best response.1y=kx if its direct variation we will use when x=2 y=4 so 4=k2 4/2=k 2=k we will use when x=4 y=2 so 2=k4 2/4=k 1/2=k when x=8 y=1 1=k8 1/8=k as we see k is constantly changing so...this is not direct variation

Best ResponseYou've already chosen the best response.1y=k/x inverse variation when x=2 y=4 4=k/2 4*2=k 8=k when x=4 y=2 2=k/4 2*4=k 8=k when x=8 y=1 1=k/8 1*8=k 8=k so yes its inverse variation k=8
