So why most x square? so you can try to find two tension line that intercept perpendicular thiss this graph look symmetric so i kind of assumed that if this tension lines has a point, actually host this one should be and actually most negativity.
00:36
So if you have x e t good, so the other point should be ex he was never fifty by most square self example this point.
00:49
Hey, this is point being.
00:53
We're trying to find the question of the tension line the equation.
00:57
First of all, let's try to figure out slope the slope is shooting.
01:04
Despues the y prime me most to x on.
01:07
This will tell you the slow no so slow off this tension line that passed through the point eight should be on shooting.
01:20
And here the slope should be active duty.
01:26
And because if they're if they're proper different to each other, this product, the slope should be attentive.
01:31
One some primitive means a product.
01:34
They're so which is that that you're forty square should be one.
01:40
So that tell us, tio no.
01:46
So so i should be negative one, particularly the product of a slope should be that one so that he tells he was prosser minus one over two.
01:58
So here's how the point, eh? will be won over to one over.
02:04
Foreign point b will be nephew fund over two and one over four.
02:09
Now, where do this'll i intercept.
02:13
So we already have on the slope of the off this line will be one...
