  1. Chapter 1, Section 6 Midpoint and distance in the coordinate plane

  2. Finding the Coordinates of a Midpoint • Midpoint Formula: • Endpoints (-3,-2) and (3,4)

  3. Step 2 Use the Midpoint Formula: Example 2: Finding the Coordinates of an Endpoint M is the midpoint of XY. X has coordinates (2, 7) and M has coordinates (6, 1). Find the coordinates of Y. Step 1 Let the coordinates of Y equal (x, y).

  5. Finding distance on a coordinate plane. • Distance Formula D = • Endpoints (-3,1) and (3,5)

  6. Distance Formula • http://www.youtube.com/watch?v=YeNqkeYwX_U&feature=related

  7. Pythagorean Theorem Can also be used to find distance on a coordinate plane! a² + b² = c²

  8. Example 4: Finding Distances in the Coordinate Plane Use the Distance Formula and the Pythagorean Theorem to find the distance, to the nearest tenth, from D(3, 4) to E(–2, –5).

  9. Practice! Find Midpoint Find Distance
