Question

Calculate the constant of variation if y varies directly as x.

Answer 1

Answer:

k = - $\frac{3}{2}$

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, thus

k = $\frac{y}{x}$ = $\frac{-3}{2}$ = - $\frac{3}{2}$

Answer 2

The answer is A -3/2
