A set designer is hammering nails along the top edge of a wall with a length of $6x$ feet, where $x$ is an integer, that will be used to hang garland. The designer hammers the first nail at the left edge of the wall. The designer then hammers an additional nail every $\frac{6}{11}$ feet along the entire length of the wall, starting from the first nail and with the last nail being hammered at the right edge of the wall. Which equation best represents this situation, where $y$ is the number of nails the designer hammers along the entire length of the wall?

A

$y=11x+1$

B

$y=11x$

C

$y=\frac{6}{11}x+1$

D

$y=\frac{6}{11}x$
