Answer:
Points A(4,0,4),B(1,2,3),C(−2,4,2) are collinear
Step-by-step explanation
formula to check whether these three points are collinear or not
AB+BC=AC
to find AB the equation is
(x

−x

by substituting the values in (1) we will get
AB = 3.7
similarly for BC and AC
BC=3.7
AC=7.4
hence finally its is known that these points are collinear
the answer will be Both Assertion & Reason are individually true & Reason is correct explanation of Assertion.
