we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx
where
k is the constant of proportionality
In this problem we have
For
y=24 ------> x=8
y=3 -----> x=1
Find the value of k
K=y/x
For y=24 and x=8
k=24/8
k=3
For y=3 and x=1
k=3/1
k=3
The value of k is the same in both cases
that means ------> is a proportional relationship
Part B
The constant of proportionality is 3
Part C
The equation is equal to
y=3x
