#y=10/x#

#"the initial statement is "yprop1/x#

#"to convert to an equation multiply by k the constant of"# #"variation"#

#y=kxx1/xrArry=k/x#

#"to find k use the given condition"#

#y=5" when "x=2#

#y=k/xrArrk=yx=5xx2=10#

#"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=10/x)color(white)(2/2)|)))#
