The axe hit her. The slash visual overlapping with her body and the position of the ghost's hands suggests that.
The next page, while I think not really adding much to the "being slashed" idea, is the action of pulling out the axe, probably after slashing (blue arrow). If the author wanted to tell us that the ghost stopped before hitting her, then it would've been better if there are no movement lines(?) as pointed by the red circle of obviousness.
