Right here!

Slide 2

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

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 here!!!

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
