We are going to be looking at solving for the midpoint of a line given two points on that line, or the end points of the line.
00:11
And the given points here are 2006, 7 ,505, and 2012, 3 ,335.
00:20
And in this situation, the x values are years, and the y values are dollars, in millions.
00:40
So what we're going to do is use the midpoint formula.
00:43
And the midpoint formula is written up here.
00:45
We have, oops, we have x1 plus x2 divided by 2, comma y1 plus y2 divided by 2.
00:55
And what that means is, first of all, we have to label our coordinates.
01:01
This is the first coordinate.
01:02
So this is going to be my x1, y1.
01:05
And this is going to be my second coordinate.
01:07
So x2.
01:08
Y2.
01:09
Now i'm going to put that into the midpoint formula and solve for my middle coordinates, my midpoint coordinate of this line segment.
01:20
So my first is going to be using x1 plus x2.
01:26
So x1 is 2006 plus x2 which is 2012.
01:32
So that should go there.
01:34
And then my y values, y1, which is 7 ,505 plus y2, which is 3 ,335 divided by 2.
01:47
And i'm going to add...
