PLEASE HELP ASAP!!!! I’ll give brainliest!!! (I accidentally pushed on the last answer idk if it’s right or not)

Answer:
Table 1
Step-by-step explanation:
To determine if it is proportional, y/x must be constant
Table 1
y/x = .5/1 = 1/2
1/2 =
3.5/7 = 1/2
4/8 = 1/2
This is constant
Table 2
y/x = 1/3
2.5/ 7.5 = 1/3
4/15 = 2/5 so it is not constant
Table 3
y/x = 12/3 =4
15/6 =5/2 not constant
Table 4
y/x = 7/2
9/3 = 3 not constant
