If a translation of T2, -7(x, y) is applied to abc, what are the coordinates of B

B' =( 3,-12)

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)

your answer is b hope that
