Unformatted text preview: A . 6. (11.5, 22) Find the parametric equation of the line through the origin that is parallel to the line given by x = 2 t , y =1 + t , z = 2. 7. (11.5, 52) Let L be the line that passes through the point ( x , y , z ) and is parallel to v = ( a, b, c ), where a , b , c are nonzero. Show that a point ( x, y, z ) lies on the line L if and only if xx a = yy b = zz c . These equations, which are called the symmetric equations of L , provides a nonparametric representation of L . 1...
