The value missing number is 16 if the y is proportional to x and relation becomes y = 2x.
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
y ∝ x
y = kx
k is the constant of proportionality:
Plug y = 10 and x = 5 to find the value of k:
10 = 5k
k = 2
y = 2x
Plug x = 8
y = 2(8)
y = 16
Thus, the value missing number is 16 if the y is proportional to x and relation becomes y = 2x.
