====================================================

Step-by-step explanation:

The translation rule used here is
$(x,y) \to (x-1, y-1)$

The x-1 refers to shifting 1 unit to the left, i.e. subtract 1 from the x coordinate.

The y-1 means shift 1 unit down.

So we have

$(x,y) \to (x-1,y-1)\\\\(-1,9) \to (-1-1,9-1)\\\\(-1,9) \to (-2,8)$
