A
given that y varies directly as x, then the relationship is
y = kx ← k is the constant of variation
To find k use the given condition x = 3 when y = 24
y = kx ⇒ k = [tex]\frac{y}{x}[/tex] = [tex]\frac{24}{3}[/tex] = 8
y = 8x
as x and y vary directly, then if x = 3 and y = 24 , the option A IS THE CORRECT, Y = 8X, y = 8*3 = 24
