ANSWER :
B'(4, 10)
EXPLANATION :
Since we are asked to find the location of the final point B', we will focus on point B only.
Point B has coordinates of (2, 9)
The transformation is 2 units to the right, so the x-coordinate will increase by 2 and 1 unit upward, so the y-coordinate will increase by 1 unit.
Then :
![(2+2,9+1)\rightarrow(4,10)](https://img.qammunity.org/2023/formulas/mathematics/college/j9c5i1267flyqdoy7jokay6j94iezbbx0c.png)
