To find whether the points are collinear I am using slope method .

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

Slope for points (4,3) and (5,1).
m= (1-3)/(5-4) = -2

Slope for points (5,1) and (1,9).
m=(9-1)/(1-5) = 8/(-4) = -2

The slopes are equal with a common point (5,1) hence they are collinear .

You can also use distance method . Refer the picture .

Hope you are able to understand.
