A) All real values of t
B) Some real values of t
C) \[t=\frac{-3\pm \sqrt{3}}{6}\]
D) None of these
Correct Answer: D
Solution :
The given point lies on the line \[x+y=2\], if \[3{{t}^{2}}+3t+3=0\]. Here discriminant 9 ? 12< 0 Therefore the value of t is imaginary. Thus the given point cannot lie on the line.
