Question

Does the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the table.

(I cant post the picture so I'll try and make my own table)

(x) 6 l 8 l 12 l 20
_____________
(y) 9 l 12 l 18 l 30

A: Inverse Variation; xy= 54

B:Inverse Variation; xy= 1.5

C:Direct Variation; y=1.5x

D: Direct Variation; y= 2/3x

Answer 1

The answer is c. Direct variation; y=1.5x

Explanation:

Answer 2

9/6 = 1.5

12/8 = 1.5

answer is C Direct variation, y = 1.5x
