Are you give an equation for this or is that all you are given?

To go from -5 to -1, we moved 4 to the right
to go from 4 to -1, we moved 5 to the left, so
(x,y) ---> (x+4, y-5)
then (-4,5) ---> (0,0)

well first the amount of translation when (-5,4) is moved to (-1,-1) what amount of translation is this in terms of x-axis? Answer to that is it moved 4 points or units towards right on x-axis.
In terms of y-axis it moved from 4 to -1 so it moved 5 points down. So in very simple way, it can be said the translation is 4 right, 5 down.
So the image of point (-4,5) after it is moved 4 right and 5 down would be point (0,0) because you do (-4,5) will be translated to (-4+4, 5-5).
