Midpoint Formula The midpoint M of a line
segment with endpoints A and B
is 1. Find the midpoint of
the segment with the given endpoints. (-3, -1)
and (5, 2) 2. Find the midpoint of the
given line segment.

• HINT FOR MULTIPLE CHOICE!
• Plot ordered pairs on a coordinate plane
• and use a MEASURING technique.
• Measure the length of the segment with another
  paper. Fold in half. Mark the middle.
• 3. What are the coordinates of the midpoint of a
  line segment with the given endpoints? (4, -1)
  and (-2, 7)
• A. (6, -8)
• B. (3, -4)
• C. (2, 6)
• D. (1, 3)
