Slant Asymptote Exercises

Hello. I was going through the calculus practice areas looking for slant asymptote exercise, and I couldn't find any.

This site has help me test into Calculus with any prior math experience past fractions. But it let me down this time. I searched extensively for slant asymptote exercises and found none. And low and behold, on the test, a slant asymptote. 

It's probably too late to help me but maybe it can help someone else.

Thanks Jason
