Either table c or table d shows a proportional relationship table c x 2,4,6,8 y 1,3,5,7 table d x 2,6,8,10 y 1,3,4,5

Table D

Step-by-step explanation:

1)To verify a proportional relationship. You must simply divide "y" coordinate over "x" coordinate like this: . This constant K remaining the same, displays a proportional relationship between them.

Verifying C

Not Proportional

So let's check for D

Proportional :)

Geometrically, when there's a proportional relationship the line passes through the Origin. Check the graph for table D.
