Answer:
The correct option is 3.
Step-by-step explanation:
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.
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
For table 1,
[tex]\frac{y_1}{x_1}=\frac{8}{4}=\frac{2}{1}[/tex]
[tex]\frac{y_2}{x_2}=\frac{11}{7}[/tex]
[tex]\frac{2}{1}\neq \frac{11}{7}[/tex]
Table 1 does not represents a proportional relationship.
Similarly,
For table 2,
[tex]\frac{25}{5}\neq \frac{49}{7}[/tex]
Table 2 does not represents a proportional relationship.
For table 3,
[tex]\frac{3}{6}=\frac{5}{10}=\frac{7}{14}=\frac{1}{2}[/tex]
Table 3 represents a proportional relationship.
For table 4,
[tex]\frac{6}{3}\neq \frac{11}{8}[/tex]
Table 4 does not represents a proportional relationship.
Only table 3 represents a proportional relationship. Therefore the correct option is 3.
