The vertices of a square are W(3, 3), X(3, –3), Y(–3, –3), and Z(–3, 3). The square will be dilated using a scale factor of 2. What will be the coordinates of the image?
W′(1.5, 1.5), X′(1.5, –1.5), Y′(–1.5,–1.5), Z′(–1.5, 1.5)
W′(5, 5), X′(5, –5), Y′(–5, –5), Z′(–5, 5)
W′(6, 6), X′(6, –6), Y′(–6, –6), Z′(–6, 6)
W′(9, 9), X′(9, –9), Y′(–9, –9), Z′(–9, 9)
