Firstly let s start off with a simple video clip: More video

Slide 3
Now that you have seen the video, its time to introduce: The
Midpoint Formula
Slide 4
For example, when you have 2 endpoints: [ A(-1, 2) and B(3,
-6)], x 1 and x 2 would replace -1 and 3 respectively; y 1 and y 2
would then replace 2 and -6. Continued Find out why here
Slide 5
Solve each side separately (easier). For the x side: (-1) + 3 =
2 2/2 = 1
Slide 6
Then, for the y side: 2 + (-6) = -4 (-4)/2 = -2
Slide 7
The answer for the midpoint would be: Midpoint (1, -2) Thats
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.
Thanks for viewing our awesome PowerPoint slide! More stuff

Slide 10
At each endpoint, there are 2 values: x and y, because they are
in the area between the x-axis and y-axis. So, value for A would be
x 1 and y 1, while B would be x 2 and y 2. Not A = x 1 and x 2, B =
y 1 and y 2. Back to slide
