Problem: Two particles are moving in the xy-plane. The move along straight lines at constant speed. At time t, particle A's position is given by x=t+2, y=1/2t-3 and particle B's position is given by x=12-2t, y=6-1/3t.
(a) Find the equation of the line along which particle A moves.
(b) Find the equation of the line along which particle B moves.
(c) Find the time (value of t) at which the distance between A and B is minimal.

NEED HELP PLEASE.. :)
