It really depends on a number of factors. I assume the the slice that you are taking about is primarily backspin (not sidespin). A fast, low-trajectory slice will tend to skid and stay low and continue moving forward (with topspin!). A shot, with heavy underspin, that hits the court at a steeper angle will tend to sit up and stop or slow its forward progress.
If the backspin, relative to the forward speed, of the ball is great enough, the ball will bounce backward since it is still spinning in the same direction (instead of converting to topspin as most shots do).
Note that (vertical-axis) sidespin will NOT affect the bounce direction. The presence of sidespin will cause the ball to break left or right prior to the bounce but has NO effect on the the bounce direction itself. It is the presence of spiral spin (nor sidespin) that will cause the ball to jump left or right on the bounce.
