Example of Intersecting Lines

Описание: Multivariable Calculus: Consider the line L1 with symmetric equations (x-1)/2 = (z+1)/-1, y=2. Determine if the following lines are parallel, equal, intersecting, or skew. (a) (x-5)/2 = (y-2)/1 = (z+3)/-1, (b) (z-1)/2 = (y-1)/1 = z/-1, and (c) x(s) = -19 + 10s, y(s) = 2, z(s) =9 -5s.
