Answer:

y = 6

Explanation:

given y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

to find k substitute x = 8 when y = 24 into the equation

24 = 8k ( divide both sides by 8 )

3 = k

y = 3x ← equation of variation

when x = 2 , then

y = 3x = 3 × 2 = 6
