(d) The line through the point (1 , 3 , 2) parallel to the line x = 2 3 t y = 1 + 3 t z = 2 2 t. 4. For each pair of lines in the plane given below, decide whether they are parallel or if not, ±nd their point of intersection. (a) x + y = 3 and 3 x 3 y = 3 (b) 2 x 2 y = 2 and 2 y 2 x = 2 (c) x = 1 + 2 t y = 1 + t and x = 2

Find the points at which the line with parametrization −→ p ( t ) = (3 + 2 t, 7 + 8 t, − 2 + t ) that is, x = 3 + 2 t y = 7 + 8 t z = − 2 + t intersects each of the coordinate planes. 6. Determine whether the given lines intersect: (a) x = 3 t + 2 y = t − 1 z = 6 t + 1...
