The coordinates of the endpoints of PQ are P(−2, 4) and Q(4, 1). On the same set of axes, label and state the coordinates of P"Q", the image of PQ under a T 4, 0 reflect y = −1.

Answer 1

P(-2,4), Q(4,1) ---> T(4,0) = P(-2+4,4+0),Q(4+4,1+0) = P(2,4),Q(8,1)

transform over y = -1 ---> distance between 4 and -1 is 5, so to flip over -1 is to flip 5 under -1 or -6: P(2,-6)

distance between 1 and -1 is 2, so to flip over -1 is to flip 2 under -1 of -3: Q(8,-3)
