Q change to Q'
the coordinate of Q is (-2, 4)
the coordinate of Q' is (-5, -2)
so the change in the x- coordinate is,
= -5 - (-2)
= - 5 + 2
= -3
so it translated 3 unit in left side
so, the change in the y coordiante is,
= -2 - 4
= -6
so it is translated 6 unit down.
so the correct answer is option A
