The path of one moving particle is given by x = 1 - 2t, y = 3t, z = 3 - t. A second particle's trajectory is given by x = 1 + t, y = t, z = 3 - 3t. a) Write the location of each particle at time t = 0. b) Write the location of each particle at time t = 1. c) Write an equation of the plane in the form ax + by + cz = d containing the paths of the particles
