Explanation:
#"the initial statement is "yprop1/x#
#"to convert to an equation multiply by k the constant"#
#"of variation"#
#rArry=kxx1/x=k/x#
#"to find k use the given condition"#
#y=12" when "x=-9#
#y=k/xrArrk=yx=12xx-9=-108#
#"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=-108/x)color(white)(2/2)|)))#
