Question

The set of points W(4, 4), X(6, 2), Y(-8, 16) are collinear and the line has a slope of ____.

Answer 1

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 :-

$m=\frac{d-b}{c-a}$

Now, the slope of line passing through W(4, 4), X(6, 2) is given by :-

$m=\frac{6-4}{2-4}=\frac{2}{-2}=-1$

Hence, the slope of line passing through W(4, 4), X(6, 2), Y(-8, 16) =-1
