Answer :
We have three points given A(16, – 18), B(3, – 6), C(– 10, 6)
To Prove: Given Points are collinear
Proof: AB[(16, – 18),(3, – 6)], BC[(3, – 6),(– 10, 6)], CA[(– 10, 6),(16, – 18)]
Formula used: The slope of the line =
The slope of line AB =
AB =
The slope of line BC =
BC =
The slope of line CA =
CA =
Here, AB = BC = CA
Hence, The Given points are collinear.
