# Mathematics : Linear Algebra Question

Determine whether the lines are coincident, parallel,

intersecting, or skew. If the lines intersect, find the point of

intersection.

a) l1: (2,-4,0)+ t<6,2,-2) and l2: x=5-t, y=1-1/3t,
z=2+1/3t
b) l1: x=2t, y=3-2t, =-1+5t and l2: (3,0,-2) +
t<1,0,1>

c) l1: (3,1/2,0) + t<2,-3/4, 2> and the line through the

points P(4,0,2) and Q(-5,3,-4)
