C d with vertices of these is a tropsoid so find the slope of a to b so x y negative 4 negative 5 negative 3 0 so that would be negative 5 over no positive 5 over positive 1 so that would be 5 the slope of d to c so 5 1 and 0 2 so 1 down five.
00:34
So that would equal negative one fifth.
00:38
Find the slope of b to c.
00:41
So negative three, zero and zero two.
00:46
So that would be two and three.
00:53
Okay.
00:55
So i have a negative slope and a positive slope.
00:57
Find the slope of a to d.
00:59
So negative four, negative five.
01:03
And then d is five.
01:08
So that would be negative 4.
01:14
Oh no, that would be a positive 6.
01:24
And then this one would be a positive 9.
01:27
So that would be 2.
01:32
I'm sorry, 6 over 9, which equals 2 thirds...
