Naily [24]

Answer:

(-2, 3)  

Step-by-step explanation:

A is translated from (5, 1) to A' at (6, -2).

That is, it moves <em>one unit to the right and three units down</em>.

B is also translated to B' one unit to the right and three units down to (-1, 0).

B must be <em>one unit to the left and three units above B'</em>.

Thus, the coordinates of B are (-2, 3).

The diagram below shows the translation of side AB of ∆ABC to its new location at A'B'.
