1 1.7 Midpoint and Distance in the Coordinate Plane 9/22/10 You can use formulas to find the midpoint and the length of any segment in the coordinate plane. Number LineCoordinate Plane

2 Finding the Midpoint Segment AB has endpoints at -4 and 9. What is the coordinate of its midpoint?

3 Finding the Midpoint Segment EF has endpoints E (7, 5) and F (2, -4). What are the coordinates of its midpoint M?

4 Finding an Endpoint The midpoint of segment CD is M(-2, 1). One endpoint is C (-5, 7). What are the coordinates if the other endpoint D?

5 Distance Formula The distance between two points A(x 1, y 1 ) and B(x 1, y 1 ) is

6 Finding Distance What is the distance between U(-7, 5) and V(4, -3)? Round to the nearest tenth?

7 More Practice!!!!! Classwork – Textbook p. 54 #7 – 29 odd. Homework – Textbook p. 54 #6 – 30 even.
