Lesson of the week
Coordinate geometry
From the study guide Midpoint coordinates
Study guide for Grades 8 to 10: 2 worked examples and 2 practice questions. Average the x-coordinates separately from the y-coordinates.
- M = ((x₁ + x₂)/2, (y₁ + y₂)/2)
- Average the x-coordinates separately from the y-coordinates.
- Example: Find only the x-coordinate of the midpoint of (19, -12) and (-12, 11). Answer: 3.5.
