    What are the vertex points of the image?

    1. Quadrilateral PQRS is dilated with a scale factor of 0.5. The vertex points of the preimage are P(2, 5), Q(5, 4), R(4, 1) and S(0, 0). What are the vertex points of the image? a. P’(5, 2), Q’(4, 5), R’(1, 4), S’(0, 0) b. P’(1, 2.5), Q’(2.5, 2), R’(2, 0.5), S’(0, 0) c. P’(4, 10), Q’(10, 8)...
