Answer:

y = -
(3)/(2) x

Explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = - 4, y = 6, thus

6 = - 4k ( divide both sides by - 4)


(6)/(-4) = k, or k = -
(3)/(2)

y = -
(3)/(2) x ← equation of variation
