For this problem, we've been asked to find the midpoint of two different line segments.
00:05
Now, each line segment, we have the end points for.
00:09
How can we use those to find the midpoint? well, let's do just a sample picture.
00:14
This is not one of our two cases.
00:15
This is just a generic line.
00:17
Let's say i have two points, and i have the line connecting them.
00:22
Well, by visual inspection, the midpoint's going to be somewhere about there.
00:26
What does that look like when i'm looking at the endpoints? first, let's look at x's.
00:32
For my first point, my x coordinate is here.
00:35
The second one is here.
00:36
So going from point a to point b, i'm traveling this far along my x -axis.
00:42
Well, my midpoint is going to be the halfway point between those two.
00:48
The number halfway between two other points is the average.
00:52
So the x coordinate of my midpoint is the average of the x's of my end points of the line segment...
