Question

Which table shows
a proportional relationship between x and y?

Answer 1

Table 2

Explanation:

Table 2 shows a proportional relationship between x and y.

The values are in direct proportion.

The condition for values
`(x_(1),y_(1) )` and
`(x_(2),y_(2) )` is:

`(x_(1) )/(y_(1) )=(x_(2) )/(y_(2) )`

Clearly,
`(5)/(75)=(8)/(120) =(10)/(150)=(1)/(15)`

Hence, all the values are in the same proportion, the second table shows the proportional relationship between x and y.
