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=50" and " x=4#
#y=kxrArrk=y/x=50/4=25/2#
#"the equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=(25x)/2)color(white)(2/2)|)))#
