Answer:

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

Step-by-step explanation:

If y varies directly with x, then from the relation of direct variation we can write y ∝ x

Now, converting the variation relation to equation relation,

⇒ y = kx  ........... (1) {Where k is the constant of variation}

Now, given that at y = - 3, x = 2 and this solution will satisfy the equation (1).

Hence, - 3 = 2k

⇒ [tex]k = - \frac{3}{2}[/tex] (Answer)
