A translation is when all the points of an image are moved by a certain distance horizontally and a certain distance vertically. If we can find the exact rule of translation from point A and A' (A prime, the point A after the translation), then we can do the reverse to B' to get the coordinate for B.

Finding the Rule of Translation

We can find how A turns into A' by essentially doing A' - A.

[tex]x: 6 - 5 = 1\\y: -2 - 1= -3[/tex]

Now we know that the translation rule is to move the image 1 unit to the right and 3 units down. Let's apply the reverse of this translation to B'.

Reversing the Translation

B' will turn into B by doing the reverse of the translation: moving the image 1 unit to the left and 3 units up. Let's apply this:

[tex]x: -1 - 1 = -2\\y: 0 + 3 = 3[/tex]

The coordinates of B are (-2,3).
