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=1" when "x=2
y=kxrArrk=y/x=1/2
"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=1/2x)color(white)(2/2)|)))
"when "x=4" then"
y=1/2xx4=2
