Question

Either table C or Table D shows a proportional relationship. Plot all the points from the table that shows a proportional relationship. I'll post a picture of the graph. Table C is ( X= 2,4,6,8) and Y= ( 1,3,5,7). Table D is ( X= 2,6,8,10) and Y= ( 1,3,4,5).

Answer 1

Explanation:

A proportional relationship is a straight line through the origin that grows at a constant rate

For table C

The constant of proportionality is y/x

2/1 = 4/3 = 6/5 = 8/7 This is not true so this is not proportional

For table D

The constant of proportionality is y/x

1/2 = 3/6 = 4/8 = 5/10 This is true so this is proportional
