Answer:
C
Explanation:
In a proportional relationship, the constant of proportionality k is:
k = y/x
Check this ratio for each of the values
A)
7.5/5 = 1.5 , 19.5/13 = 1.5 , 33/23 = 1.4347.... ← Thus not A
B)
9.5/8 = 1.1875 ← Thus not B
C)
12/8 = 1.5 , 13.5/9 = 1.5 , 27/18 = 1.5
Therefore, the table with k = 1.5 is Table C.
