The points (p - 1, p+2), (p, p+1), (p+1, p) are collinear for
p = 0
p = 1
p = - 1 / 2
Any value of p
The correct option is D Any value of p For 3 points to be collinear. (i) Either the slope of any two of the 3 points should be equal to the slope of any other two points. Or (ii) The area of the triangle formed by the three points should be equal to zero.
