We are given the coordinates of a triangle and are asked for the coordinates of a new point after translating it 2 units to the right and 1 unit up. Therefore, the changes in the coordinates are as follows, we add 2 units to the x coordinates and 1 to the y coordinates:
[tex]\begin{gathered} A^{\prime}=(4+2,2+1)=(6,3) \\ B^{\prime}=(2+2,7+1)=(4,8) \\ C^{\prime}=(10+2,5+1)=(12,6) \end{gathered}[/tex]Therefore, the location of final point B´ is (4,8)
