$inverse variation$ $"inverse variation"$

Explanation:

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

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

$the standard form of an inverse variation equation is$ $"the standard form of an inverse variation equation is"$

$∙ x y = \frac{k}{x} \leftarrow k is the constant of variation$ $•color(white)(x)y=k/xlarrcolor(blue)"k is the constant of variation"$

$\Rightarrow y = \frac{4.2}{x} represents inverse variation$ $rArry=4.2/x" represents inverse variation"$

$with k = 4.2$ $"with "k=4.2$
