Answer:
B' =( 3,-12)
Step-by-step explanation:
In translation, a point K(x,y) can be translated using the rule T₁(a,b) to form K'(x+a,y+b)
The translation rule is given as T------ (2,-7)
The coordinate for B (1,-5)
Applying the translation B (1,-5) ---------T (2,-7)---------B'( 1+2, -7+-5)=(3,-12)
B' =( 3,-12)
