Explanation:
#"the initial statement is "ypropx#
#"to convert to an equation multiply by k the constant"#
#"of variation"#
#rArry=kx#
#"to find k use the given condition"#
#y=4" when "x=16#
#y=kxrArrk=y/x=4/16=1/4#
#"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=1/4x)color(white)(2/2)|)))#
#"when "x=6" then "#
#y=1/4xx6=6/4=3/2#
