k = gh_doc.RelevantObjectAtPoint(i.Attributes.Pivot)

This is not a good way. It's the loooong way around and it will fail if there's another object on top of the one you're working with.

I'd go for something along the lines of:

foreach (IGH_DocumentObject obj in GrasshopperDocument.Objects)
{
  var slider = obj as Grasshopper.Kernel.Special.GH_NumberSlider;
  if (slider == null) continue;
  slider.Attributes.Selected = true;
}

David's code is much nicer and more readable but if you end up doing a lot of GH document manipulation you can be quite efficient with Linq:

GrasshopperDocument.Objects.OfType<Grasshopper.Kernel.Special.GH_NumberSlider>().ToList().ForEach(s => s.Attributes.Selected = true);
