1.) Choose the algebraic description that maps the image ΔABC onto ΔA′B′C′. (x, y) → (x, y-1) (x, y) → (x-1,y) (x, y) → (x, y+1) (x, y) → (x+1,y) 2.) Choose the algebraic description that maps the image ΔABC onto ΔA′B′C′. (x, y) → (x+4,y) (x, y) → (x, y+4) (x, y) → (x-4,y) (x, y) → (x, y-4) 3.) Choose the algebraic description that maps the image ΔABC onto ΔA′B′C′. (x, y) → (x-7,y-4) (x, y) → (x+7,y+4) (x. y) → (x-7,y+4) (x, y) → (x+7,y-4) 4.) Choose the composition of translations that maps the image ΔPQR onto ΔP′Q′R′. (x, y) → (x+6,y+3) (x, y) → (x-6,y+3) (x, y) → (x-6,y-3) (x, y) → (x+6,y-3) 7.)
