Let's do this question, find the midpoint of the line segment obtained by joining a three four and
point B, that's minus five, comma eight.
All right, pause the video, give it a try and then let's do it together.
All right, we're back.
Let's do it together now over here, we have a nine segment.
The two points are given us three comma for and minus five, comma eight.
Now we need to find the midpoint.
Right now, the midpoint divides this nine segment in the ratio.
One is two one.
Right.
So if sees the midpoint, that would mean that a C divided by CB is equal to one by one.
Right.
Therefore, we know how to find the point C right.
It would be three plus minus five by two comma four plus eight by two.
Right.
Three plus minus five divided by two and then four plus eight by two.
Right over here because it's one and one you're only to multiply because even if you multiply it does
not change.
So that's using the Formula three into one plus minus five in two, one by one plus one.
That's how you get this part over here, right.
Similarly, you have four into one plus eight in the one divided by one plus one.
That's how you get this part over here and so on.
Solving this, you will get that C that is minus one, comma six is the point that divides A B in the
ratio.
One is two one.
