(adsbygoogle = window.adsbygoogle || []).push({}); 1. Given that the two lines r1 and r2 intersect, find the value of a and hence determine the point of intersection.

r1=i+9j-3k+landa(i+j-k)

r2=4i+ak+mew(6i+5j+k)

2. Relevant equations

3. I'm a little lost with this one. Do I need to rewrite in parametric form and then cartesian form then compare i and j components. Then find values of mew and landa. Then use r1 and plug in landa value and solve for point of intersection?
