Step-by-step explanation:

Find the slope of (8,1) and (3, -4):

Slope = (y2 - y1)/(x2 - x1)

Slope = (1 + 4)/(8 - 3) = -1


Find the slope of (3, -4) and (2, -5):

Slope = (y2 - y1)/(x2 - x1)

Slope = (-4+5)/(3-2) = -1


Since the slope of the 2 lines made by the three points are the same, and one of the point being the common point

The three points are collinear (Shown)
