$yes, k = 3$ $"yes ",k=3$

Explanation:

$the standard form of a direct variation equation is$ $"the standard form of a direct variation equation is"$

$∙ x y = k x \leftarrow k is the constant of variation$ $•color(white)(x)y=kxlarrcolor(blue)"k is the constant of variation"$

$3 y = 9 x \leftarrow divide both sides by 3$ $3y=9xlarrcolor(blue)"divide both sides by 3"$

$\Rightarrow y = 3 x \leftarrow in standard form$ $rArry=3xlarr"in standard form"$

$with k = 3$ $"with "k=3$
