Midpoint and Line Segment Concepts

What is a midpoint of a line segment?

• A point that divides the segment into two unequal parts.

• A point that is directly in the middle of the line segment, cutting it into two congruent halves.

• A point that is closer to one endpoint than the other.

• A point that is outside the line segment.

Which of the following is the correct midpoint formula for two points (x1, y1) and (x2, y2)?

• ((x1 - x2)/2, (y1 - y2)/2)

• ((x1 + x2)/2, (y1 + y2)/2)

• (x1 + x2, y1 + y2)

• (x1 * x2, y1 * y2)

What is the midpoint of a line segment with endpoints (7, 3) and (-5, 5)?

• (1, 4)

• (2, 8)

• (6, 4)

• (12, 2)
