Let's do this question, which of the points is not on the line, why is it X plus four?
All right, was the video, give it a try and then let's do it together.
All right.
We're back.
I hope you've given it a try.
We need to find which among these four points is not on this line.
Right to the way forward is to substitute and check.
Right.
Whether the given point is a solution or this line or not.
All right.
Let's try to do that now.
Let's take the first case.
That's one 12.
Right.
So if you substituted, you will get Y is 12.
Right.
And over here, X is one to 18 to one plus four.
That also adds up to 12.
So this point is on this line.
What about the second option?
You will get it as white, all right, and X is one by two, so eight in the one bedroom plus four.
This also adds up to eight.
So this point is also on the line right now.
Over here, X's root of twenty seven, now eight X plus four.
Let me substitute X as route twenty seven.
So that becomes eight root twenty seven plus four and root twenty seven is three.
Root three.
Right.
So this becomes twenty four.
Root three plus four.
Let me take out four which is common and it becomes four and six root three plus one.
And that is what is given over here.
Right.
And so that's equal to white.
So yes, this point is also on this line.
What about option number four?
You will see that it's not on this line, right?
Because when you substitute it, you will get eight root two plus four.
And that is not equal to 12.
Right.
Therefore, this point over here is not on the given line.
