Question

does this data represent a direct variation or an inverse variation? x6 y 9, x 8 y 12, x 12 y 18, x 20 y 30

Answer 1

it is a direct variation because k is proportionally constant

Explanation:

direct variation is y=k.x

inverse variation is k=y.x or y=k/x

6/9 = 2/3

8/12=2/3

12/18=2/3

20/30=2/3

i even add a graph for you
