The midpoint of a line segment is the point directly in the center of the line. Here is the midpoint formula.

This is like finding the average of the x's and y's


Here are some examples:
1.) Find the center of a circle whos end points of the diameter are D(3,-2) and E (-2,4)


2.) (9,11) is the midpoint and the end points are at (x,12) and (B, y) find xy


It doesnt matter what variable is used. so dont get confused by that. Just remember to always plug in the information that you have.

Thats about all we learned on fridays class. exept that ms.Armstrong worked for her dad's candy company and her children slept in shopping carts. hehe.

Dont forget that the homework was exersise 5 and expect a quiz on midpoints and distance on wednesday. not on graphing.
