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 :-
[tex]m=\frac{d-b}{c-a}[/tex]
Now, the slope of line passing through W(4, 4), X(6, 2) is given by :-
[tex]m=\frac{6-4}{2-4}=\frac{2}{-2}=-1[/tex]
Hence, the slope of line passing through W(4, 4), X(6, 2), Y(-8, 16) =-1
