For this problem, we want to find the midpoints of two different line segments.
00:05
And we have each one, just number these one and two.
00:08
Each pair represents the end points of a line segment.
00:12
So what is the midpoint directly between each of these pairs? well, in order to do that, let's just take a moment to sketch what something like this might look like.
00:23
I'm not going to use these particular numbers.
00:25
I'm just going to pick two points.
00:26
And i'm going to draw the line between them.
00:31
Now, just visually, i can tell the midpoint's going to be somewhere about there.
00:35
If i've got these as my endpoints.
00:37
But let's think of what we have.
00:40
Okay? i'm going, on the x -axis, i'm going from coordinate one to coordinate two.
00:47
I want to go directly in the middle.
00:51
How do you find the middle of two numbers? well, that's the average.
00:56
So in order to find my x, i'm going to have to average my two x coordinates.
01:02
That's the x coordinate of that midpoint.
01:06
By the same token, look what's happening for my y coordinate...
