### Finding the Midpoint

1. 1. Right here!
2. 2.  Firstly let’ s start off with a simple video clip:Morevideolinks!
3. 3.  Now that you have seen the video, it’s time to introduce: The Midpoint Formula
4. 4.  For example, when you have 2 endpoints: [ A(-1, 2) and B(3, -6)], x1 and x2 would replace -1 and 3 respectively; y1 and y2 would then replace 2 and -6. Find out why Continued here
5. 5.  Solve each side separately (easier). For the ‘x’ side: (-1) + 3 = 2 2/2 = 1
6. 6.  Then, for the ‘y’ side: 2 + (-6) = -4 (-4)/2 = -2
7. 7.  The answer for the midpoint would be: Midpoint (1, -2) That’s the conventional method to find the midpoint. But as long as you remember that youre averaging the two points x- and y- values, you will do fine. It wont matter which point you pick to be the ‘first’ point you start with.
