Point A is located at (-4,2) and point B is located at (-1,2). What is the length of the image of AB when AB is translated 5 units right and 2 unit down?
Translating won't change the size of the figure.
The length of the line segment from (-4,2) to (-1,2) is 3. (These points are on a horizontal line and the distance from -4 to -1 is 3.)
So the length of the image is also 3.
