It would be (0, -3)
A translation means to just slide it left or right.
So, if we are translating Point A five units to the right, we would determine where our point would be at the beginning, which is (-5, -3).
On the x-axis we would count 5 units to the left (because it is negative) then we would count three units down ( not up, because it is negative)
That is where our original point A would be placed.
So when we translate, all you would do is move it over five units to the right and your point ends up being only on the y-axis which is why your x axis is 0 and your y axis is -3
I know it's kind of confusing when it is typed, but if you would like me to try and explain a little more just let me know :)
Hope this helps
