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=0.5" when "x=2#
#y=kxrArrk=y/x=0.5/2=0.25#
#"the equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=0.25x)color(white)(2/2)|)))#
