points are collinear.
Explanation of Solution
Given information:
Three points are
Formula used:
Slope,
Calculation:
Points
On taking first two points to find point-slope form of line
Here
Using slope formula to calculate slope of line
On solving
Point slope form finding below
Take any one point from first two chosen
Let take
Here
Using point-slope form formula
On solving
If third point
Then it will satisfy the equation.
So
On solving
On solving
On solving
Hence, points are collinear.
