3.In the figure. What are the coordinates of the image of point B after a translation (x+4, y-7) ?

Answer:
(5, -5)
Explanation:
The coordinate of Point B is: (1,2)
If we carry out the translation (x+4, y-7) on point B, we have:
[tex]B(1,2)\rightarrow (1+4,2-7)=B^{\prime}(5,-5)[/tex]The coordinates of the image of point B is (5, -5)
