Of the vertices of quadrilateral ab, c, d are a, and it gives all the coordinates.

Drag and drop the choices into each box to correctly complete the sentences.
00:09
The slope of a, b is what? so let's find the slope of a, b.
00:15
Okay.
00:16
So a is at negative 5, 1.
00:20
B is at negative 2, 5.
00:22
So i'm going to find the change in y over the change of x.
00:26
So going from 1 to 5 is going up 4.
00:29
And going from 5 to negative 2 is going up 3.
00:36
So the slope of a to b is 4 over 3.
00:39
Now i'm going to find the slope of b to c.
00:43
So negative 2, 5, and 5, 3.
00:47
So i'm going down 2 and i'm going up 7.
00:52
So my change of y over change of x is negative 2 over 7...
