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? m = undefined, C′D′ = 13.2 units m = 0, C′D′ = 6.6 units m = 0, C′D′ = 13.2 units m = undefined, C′D′ = 8 units

C = (10, 6) D = (10, 12) 2.2 * 10 = 22 2.2 * 6 = 13.2 2.2 * 12 = 26.4 So we have: C' = (22, 13.2) D' = (22, 26.4) Line CD and C'D' will be the same but parallel.. And since CD is a straight line, then it will be undefined. To find the distance between two points use the formula: (x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√ Here: x2=22 x1=22 y2=26.4 y1=13.2 (22−22)2+(26.4−13.2)2−−−−−−−−−−−−−−−−−−−−−√ (0)2+(26.4−13.2)2−−−−−−−−−−−−−−−−√ (0)2+(13.2)2−−−−−−−−−−−√ 0+174.24−−−−−−−−√ 174.24−−−−−√ 13.2
