2.21. If AB below is dilated at Point B by a scale factor of 2, how will the equation of A'B' compare with the equation of AB? 10 A 21 10 B -4 A. The slope of A'B' will be double the slope of AB and the y –intercept of A'B' will be shifted up 2 units. B. The slope of A'B' will be half the slope of ĀB, and the y -intercept of A'B' remains unchanged. C. The slope of A'B' will be 2 units greater than the slope of AB, and the y -intercept of A'B' will be shifted up 2 units. D. The slope of A'B' is the same as the slope of AB, and the y -intercept remains unchanged.
