Hello.
00:01
So here we are considering a quadrilateral with vertices a equal to 02, b equal to 4 negative 1, c equal to 1 negative 5, and d equal to negative 3, negative 2.
00:14
So we now want to find the slope of a, b.
00:18
So you know that this is the slope is going to be rise over and run.
00:22
So that's change in y over change in x.
00:25
So on the slope of a, b, we consider a, which is the 02, 2, and b.
00:30
Which is the point for negative 1.
00:33
Then we have that our slope is going to be, well, change in y.
00:36
That's going to be a minus 1, minus 2 over the change in x, which is going to be 4, well, minus 0.
00:46
So therefore, this is equal to minus 1 minus 2 is a minus 3 over 4...
