A Trombone. The slide allows the trombone to play lower pitches.

Marching Trombone> It looks like a large trumpet. It allows for easier marching , not having to use the slide.
A trombone has a slide. The slide allows it to do the infamous glissandos.
There is no other instrument other than the Trombone with a slide. There are variations of the trombone though. For example, there is a trombone made with a slide and valves. There are also different types of trombones. There is the bass trombone, tenor trombone, alto trombone, soprano trombone (slide Trumpet), and piccolo trombone. (Please note that the soprano trombone, or slide trumpet, does not have valves. It is also called a slide trumpet because it has the same exact range, sounds like a trumpet, and uses a trumpet mouth piece.) There has also been plastic, wooden, and metal trombones made. I hope that this helped!
