Find all horizontal, vertical, or slant asymptotes

I have been instructed to find all the horizontal, vertical or slant asymptotes of the following function:

$y={x}^{3}-4{x}^{2}$

I know there are no horizontal or vertical asymptotes, but I'm having a hard time understanding slant asymptotes. How do I figure out if there are any of those?
