Question

GEOMETRY. PLEASE HELP ASAP!! I AM STUMPED! O.o

Answer 1

The point R has coordinates (-5,-5) and the image point R' has coordinates (2,-7).

If

• -5+a=2, then a=2-(-5)=2+5=7;
• -5+b=-7, then b=-7-(-5)=-7+5=-2.

Thus, the translation rule is

(x,y)→(x+7,y-2)

or $T_{(7,-2)}(RSTU)$

If point U has coordinates (-5,1), then its image U' has coordinates (-5+7,1-2) that is (2,-1).

Answer: correct choice is B
