What are the coordinates of the midpoint of the line segment joining A(3, -7) and B(-5, 1)?
Answer and explanation
Correct answer: D. (-1, -3)
- Step 1: Midpoint = ((x1 + x2)/2, (y1 + y2)/2). Step 2. ((3 + (-5))/2, (-7 + 1)/2) = (-2/2, -6/2) = (-1, -3). Answer: (-1, -3). Why not the others: (-2, -6) forgets dividing by 2.
