lutik1710 [3]

Answer:

See below ~

Step-by-step explanation:

Question 3 : (x, y - 5)

K' = (-3, 2 - 5) = (-3, -3)
L' = (1, 4 - 5) = (1, -1)
M' = (-1, 0 - 5) = (-1, -5)
N' = (-5, -2 - 5) = (-5, -7)

Question 4 : (x + 4, y + 1)

D' = (-4 + 4, 3 + 1) = (0, 4)
E' = (0 + 4, 2 + 1) = (4, 3)
F' = (-2 + 4, -6 + 1) = (2, -5)
G' = (-6 + 4, -5 + 1) = (-2, -4)
