Answer:

C) 4

Explanation:

Given equation:

2y=8x

The above equation represents proportional relationship.

To find the constant of proportionality.

Solution:

The equation representing proportional relationship is given by:

where
represents constant of proportionality.

So, in order to find the value of
for the given proportionality relationship, we will solve for

We have:

2y=8x

Solving for

Dividing both sides by 2.

(2y)/(2)=(8x)/(2)

y=4x

∴

Thus, the constant of proportionality = 4.
