Answer:
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
