A translation is defined as:
[tex](x,y)\rightarrow(x+a,y+b)[/tex]where a represents the translation in the horizontal direction and b the translation in the vertical direction.
Since the translation given tranlates the points 4 units to the right, this means that a=4; and the translation tranlates 5 units down that means that b=-5. Hence the translation is:
[tex](x,y)\rightarrow(x+4,y-5)[/tex]Therefore the answer is C.
