Answer:

A

Step-by-step explanation:

given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

to find k use the given condition y = 2 when x = 10

k = \frac{y}{x} = \frac{2}{10} = \frac{1}{5}

y = \frac{1}{5} x ← equation of variation

when x = 40, then

y = \frac{1}{5} × 40 = 8 → A
