Jasper has outgrown the bike he rode when he was small. So, for his twelfth birthday, his parents surprise him with a five-speed Blaze Rider 20001 Jasper has never had a bike with multiple speeds before, and he is eager to learn how it works. He starts by testing the middle speed.
There is a proportional relationship between the number of times Jasper pedals, \( x \), and the number of times the wheels rotate, \( y \).
Write an equation for the relationship between \( x \) and \( y \). Simplify any fractions.
\[
y=\square
