Answer:

y = 8

Step-by-step explanation:

Given the relationship is direct then the equation relating the quantities is

y = kx ← k is the constant of proportion

To find k use the condition when y = 16, x = 4, then

16 = 4k ( divide both sides by 4 )

4 = k

y = 4x ← equation of proportion

When x = 2, then

y = 4 × 2 = 8
