It is important to remember the definition of "Translation".
A Translation is defined as a transformation that moves every point of an object a determine distance in a given direction. In Translation, the shape and the size of the object do not change.
Then, given a point:
Where "x" is the x-coordinate and "y" is the y-coordinate.
And given the following translation:
We can notice that:
2 units are added to the original x-coordinate. This indicates that the object must be moved 2 units to the right.
4 units are subtract from the original y-coordinate. This indicates that object must be moved 4 units down.
