Answer:

k = - [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Since y varies directly as x then the equation connecting them is

y = kx ← k is the constant of variation

to find k use the given condition y = - 3 when x = 2, hence

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{-3}{2}[/tex] = - [tex]\frac{3}{2}[/tex]
