Question

Polygon ABCD will be dilated by a scale factor of 2.2 with the origin as the center of dilation, resulting in the image A′B′C′D′. What will the slope and length of C'D' be?

Answer 1

The answer is A. m = undefined, C'D' = 13.2 units. When you dilate both C and D with the scale factor 2.2 with the origin as the center of dilation, their coordinates respectively become the following:C' (22, 13.2) and D (22,26.4)
The difference between 26.4 and 13.2 is 13.2. The slope is undefined since it is s vertical line. 

Hope i helped
