#"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#
