Question

The coordinates of the vertices of AHKM are H(3, -2),

K(7, -5), and M(5, -1). After a translation, the coordinates
of the vertices of the image of AHKM are H'(-3, 1), K'(1, -2),
and M'(-1, 2). What translation was performed on AHKM?

Please please help

Answer 1

• B. (x, y) → (x - 6, y + 3)

Explanation:

Find the difference of corresponding coordinates

H to H'

• x = - 3 - 3 = - 6
• y = 1 - (-2) = 3

K to K'

• x = 1 - 7 = - 6
• y = - 2 - (-5) = 3

According to above, the rule is:

• (x, y) → (x - 6, y + 3)

Correct choice is B
