The diagram shows two quadrilaterals graphed on a coordinate plane. If figure 1 (the pre-image) is dilated to produce figure 2 (the image) then what is the scale factor? A A dilation by a scale factor of 12 centered at the origin. B A dilation by a scale factor of 13 centered at the origin. C A dilation by a scale factor of 3 centered at the origin. D A dilation by a scale factor of 2 centered at the origin.
