Answer:
The rule of the translation is (x,y) -----> (x+3,y-3)
The translation is 3 units at right and 3 units down
Step-by-step explanation:
we have that
The translation of point B to point B' is
B(-6,1) -----> B'(-3,-2)
so
(x,y) -----> (x+a,y+b)
B(-6,1) ----> (-6+a,1+b)
Find the value of a

solve for a

Find the value of b

solve for b

therefore
The rule of the translation is
(x,y) -----> (x+3,y-3)
That means ----> The translation is 3 units at right and 3 units down
