- The midpoint is halfway along the segment. Average the -coordinates, then average the -coordinates.
- Across: the -coordinates are and . Their average is .
- Up and down: the -coordinates are and . Their average is .
- Put the two averages together. The midpoint is .
- Traps: forgets to divide by . and subtract instead of adding.
