Answer:

y = 36x

Step-by-step explanation:

Given that y varies directly as x, then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 18 when x = $\frac{1}{2}$ , thus

k = $\frac{y}{x}$ = $\frac{18}{\frac{1}{2} }$ = 36

y = 36x ← equation of variation
