Select the tables that show a proportional relationship between x and y.

Table 1, Purple/Blue

Step-by-step explanation:

Table 1:  Find the relationship

3/4 -> 0.75

6/8 -> 0.75

9/12 -> 0.75

Table 2:  Find the relationship

6/2 -> 3

8/4 -> 2

9/5 -> 1.8

Since table 1 has all the name quotient, that means that table 1 is a proportional relationship between x and y.
