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 6 8 12 20
y 9 12 18 30
A. inverse variation; xy = 1.5
B. direct variation; y = 1.5x
C. inverse variation; xy = 54
D. direct variation; y = 2/3X
B. Direct variation, y = 1.5x
Check: 9/6 = 12/8 = 18/12 = 30/20 = y/x = 1.5
