A fun presentation about Finding Midpoints in Coordinate Geometry.

1. Right here!

2.  Firstly let’ s start off with a simple video

3.  Now that you have seen the video, it’s
time to introduce:
The Midpoint Formula

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.

5.  Solve each side separately (easier).
 For the ‘x’ side:
 (-1) + 3 = 2
 2/2 = 1

6.  Then, for the ‘y’ side:
 2 + (-6) = -4
 (-4)/2 = -2

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 you're
averaging the two points' x- and y-
values, you will do fine. It won't matter
which point you pick to be the ‘first’ point
you start with.
