Determine if the points (1,5),(2,3)and (-2,-11) are collinear ?

Answer» Determine if the points (1, 5), (2, 3) and (– 2, – 11) are collinear
Let the given points be A( 1, 5), B(2, 3) and C(-2, -11). ThenHere, we see that AB + BC ≠ AC, BC + AC ≠ AB and AB + AC ≠ BC.Hence, the points A, B and C are not collinear.
