What is the biggest difference between an equation that has a direct variation and one that does not have a direct variation?

Can someone please help me?

Answer 2

if y varies directly as x, , another way to say it is they are directly proportional

y = k*x

line through the origin, slope k

if y does not vary directly, you have some other function , not line
