Answer:

y = - 24

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 condition y = 12 when x = - 3

k = $\frac{y}{x}$ = $\frac{12}{-3}$ = - 4

y = - 4x ← equation of variation

When x = 6, then

y = - 4 × 6 = - 24
