Answer: Table A has a proportional relationship
See the diagram below
==================================================
Step-by-step explanation:
Table A has a proportional relationship because all the points are on the same straight line. That line in this case is y = 2x
Whatever x is, multiply it by 2 and you'll get the y value
Example: If x = 4, then y = 2*x = 2*4 = 8 which gives the point (4,8)
Another phrase for "proportional relationship" is "direct variation".
