$k = \frac{1}{2}$ $k=1/2$

Explanation:

$a direct variation equation has the form$ $"a direct variation equation has the form"$

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

$y = \frac{1}{2} x is in this form thus is a direct variation equation$ $y=1/2x" is in this form thus is a direct variation equation"$

$with k = \frac{1}{2}$ $"with "k=1/2$
