Question

Prove that the points A(-1,0) B(3,1) C(2,2) D(-2,1) are the vertices of collinear

Answer 1

Answer:

The Given Vertices are Collinear.

Step-by-step explanation:

If the vertices are collinear, then the slope of two parallel sides are equal.

slope of (x1,y1) & (x2,y2) =  (y2-y1)/(x2-x1)

slope of AB = (1-0)/(3+1)  =  1/4

slope of CD = (1-2)/(-2-2) = 1/4

slope of AD = (1-0)/(-2+1) = -1

slope of BC = (2-1)/(2-3)  = -1

Here, Slope of AB = Slope of CD  & Slope of AD = Slope of BC
