1
00:00:00,680 --> 00:00:08,300
Let's do this question, find the midpoint of the line segment obtained by joining a three four and

2
00:00:08,300 --> 00:00:10,780
point B, that's minus five, comma eight.

3
00:00:11,060 --> 00:00:14,920
All right, pause the video, give it a try and then let's do it together.

4
00:00:16,020 --> 00:00:16,950
All right, we're back.

5
00:00:16,980 --> 00:00:20,210
Let's do it together now over here, we have a nine segment.

6
00:00:20,490 --> 00:00:25,100
The two points are given us three comma for and minus five, comma eight.

7
00:00:25,410 --> 00:00:27,300
Now we need to find the midpoint.

8
00:00:27,300 --> 00:00:32,130
Right now, the midpoint divides this nine segment in the ratio.

9
00:00:32,310 --> 00:00:33,270
One is two one.

10
00:00:33,270 --> 00:00:33,630
Right.

11
00:00:33,960 --> 00:00:40,190
So if sees the midpoint, that would mean that a C divided by CB is equal to one by one.

12
00:00:40,200 --> 00:00:40,580
Right.

13
00:00:40,820 --> 00:00:44,250
Therefore, we know how to find the point C right.

14
00:00:44,260 --> 00:00:50,280
It would be three plus minus five by two comma four plus eight by two.

15
00:00:50,280 --> 00:00:50,640
Right.

16
00:00:51,010 --> 00:00:56,430
Three plus minus five divided by two and then four plus eight by two.

17
00:00:56,430 --> 00:01:01,770
Right over here because it's one and one you're only to multiply because even if you multiply it does

18
00:01:01,770 --> 00:01:02,360
not change.

19
00:01:02,580 --> 00:01:09,270
So that's using the Formula three into one plus minus five in two, one by one plus one.

20
00:01:09,450 --> 00:01:11,450
That's how you get this part over here, right.

21
00:01:11,690 --> 00:01:17,580
Similarly, you have four into one plus eight in the one divided by one plus one.

22
00:01:17,580 --> 00:01:20,520
That's how you get this part over here and so on.

23
00:01:20,520 --> 00:01:26,700
Solving this, you will get that C that is minus one, comma six is the point that divides A B in the

24
00:01:26,700 --> 00:01:27,180
ratio.

25
00:01:27,180 --> 00:01:27,900
One is two one.
