Here in this problem, a, b is a line segment, its midpoint given m, that is 5 .8, 1 endpoint, that is the b, is 13, 10.
00:14
We have to find the coordinate for the other end point a.
00:19
Let the coordinate for a is x, comma, y.
00:25
Now, let's write the formula for midpoint.
00:30
The midpoint of the line segment joining the point x1 y1 and x2 y2 is that midpoint, midpoint formula will be x1 plus x2 divided by 2 comma y1 plus y2 divided by 2.
00:58
Here, the midpoint of a and b, it is x and y, a and b, we can write it that 5 .8, that's the midpoint, and here it will be x1 is x and x2 is 13.
01:18
So, x plus 13 divided by 2...
