Question
Is the given table a proportional relationship? If so, what is the constant?
- Yes =
- Yes = 3
- Yes = 5
- No
Hint:
Constant of proportionality is the constant value of the ratio between two proportional quantities.
The correct answer is: Yes = 3
Here, we have to find the constant.
To check the constant of proportionality,we use :k = y/x , where k is the constant ratio of y values to corresponding to x values.
k = 3
Yes, they have proportional relationship.
Constant =3
Hence, the correct option is (d).
We observe that all the ratio in the above tables are equal. So, these values are in a proportional relationship.
