Having trouble slipping stitches
What pattern is it or how does that whole row read?
When I’ve come across these instructions they are usually part of a skpo (slip one, knit one the pass the the slipped stitch over). I just tend to keep the yarn at the back for the knitted stitch but as said above the whole instruction may reveal more 
Generally, you don’t slip purlwise for a decrease though, it makes the top st twisted and doesn’t lie flat. But if you were to slip a stitch and not do anything to it until the next row, you’d slip purlwise.
