Read each question carefully and use the midpoint formula to find the midpoint of the given line segments. Show all your work.
1. Write down the midpoint formula for a line segment with endpoints (x₁, y₁) and (x₂, y₂).
2. Find the midpoint of the line segment with endpoints (3, 5) and (7, 9).
x-coordinate: (3 + 7) / 2 =
y-coordinate: (5 + 9) / 2 =
Midpoint: ( , )
3. What is the midpoint of the segment connecting (-2, 4) and (6, -8)?
