Question

What is the constant of variation, k, of the direct variation, y = kx, through (–3, 2)?

Answer 1

$\underline{\underline{\textsf{Answer :}}}$

$\textsf{Given variation is y = kx}$

$\textsf{We satisfy y = kx by (-3, 2)}$

$\textsf{2 = k ( - 3 )}$

$\implies \boxed{\textsf{k =} \textsf{-}\dfrac{\textsf{2}}{\textsf{3}}}$

$\textsf{which is the required value of k.}$

Answer 2

We satisfy y = kx by (-3, 2)

\textsf{2 = k ( - 3 )}2 = k ( - 3 )

\implies \boxed{\textsf{k =} \textsf{-}\dfrac{\textsf{2}}{\textsf{3}}}⟹

k =-

3

2

\textsf{which is the required value of k.}which is the required value of k.
