"inverse variation"

Explanation:

"the standard form of a direct variation equation is"

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

"the standard form of an inverse variation equation is"

•color(white)(x)y=k/xlarrcolor(blue)"k is the constant of variation"

rArry=4.2/x" represents inverse variation"

"with "k=4.2
