We need to find a table of ordered pairs that represents a proportional relationship.
Proportional relationship: It means y-values are proportional to x-values.


where, k is constant of proportionality.
For table 1,



Table 1 does not represents a proportional relationship.
Similarly,
For table 2,

Table 2 does not represents a proportional relationship.
For table 3,

Table 3 represents a proportional relationship.
For table 4,

Table 4 does not represents a proportional relationship.
Only table 3 represents a proportional relationship. Therefore the correct option is 3.
