Verified Answer :

the answer for p is (7,17.5)
Q is (7,3.5) I have the same test

Answer: The answer is P'(7, 17.5) and Q'(7, 3.5).

Step-by-step explanation:  Given that a line segment PQ is dilated with a scale factor of 3.5 where origin is the centre of dilation.

The end points of segment PQ are P(2, 5) and Q(2, 1).

Therefore, after dilation, the coordinates of the end points become

\(P'=(2\times 3.5,5\times 3.5)=(7, 17.5),\\\\Q'=(2\times 3.5,1\times 3.5)=(7,3.5).\)

Thus, the coordinates of P' are (7, 17.5) and the co-ordinates of Q' are (7, 3.5).
