slope of cd=slopeof ad
(3-(t+1))/(2-t/3) = (1-(t+1))/(3-t/3)
check that, solve for t.
The points A(3;1), B(1;-2) and C(2;3) in a cartesian plane are given.
If CD is parallel to AD with D(t/3;t+1) determine the value of t

If CD is parallel to AD, then CD meets AD at D. But parallel lines never meet!
