y=1/3x

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=2" when "x=6

y=kxrArrk=y/x=2/6=1/3

"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=1/3x)color(white)(2/2)|)))
