Answer: -1
Step-by-step explanation:
Given: The set of points W(4, 4), X(6, 2), Y(-8, 16) are collinear
The slope of a line passing through points (a,b) and (c,d) is given by :-
![m=\frac{d-b}{c-a}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7Bd-b%7D%7Bc-a%7D)
Now, the slope of line passing through W(4, 4), X(6, 2) is given by :-
![m=\frac{6-4}{2-4}=\frac{2}{-2}=-1](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B6-4%7D%7B2-4%7D%3D%5Cfrac%7B2%7D%7B-2%7D%3D-1)
Hence, the slope of line passing through W(4, 4), X(6, 2), Y(-8, 16) =-1
