Explain your reasoning · Coordinate distance

Point A is (−4, 2) and point B is (3, 2). How far apart are the points? Describe the segment and explain how you found its length.

Open a sample approach and scoring guide

One possible approach: 7 units. The points share y = 2, so the segment is horizontal. Its length is the absolute difference between x-coordinates: |3 − (−4)| = 7.

2-point guide: 1 point for recognizing the shared coordinate and horizontal segment; 1 point for 7 units with an absolute-difference explanation.

Try the problem before opening the example. A tutor or teacher can use the guide to discuss your representation and reasoning.
