Linear algebra: intersectionHi all I recently started linear algebra and my prescribed book seems to require some 3dimensional geometry knowledge which i've never touched... Any idea how to go about this? #2 20121006 06:07:00

Re: Linear algebra: intersectionhi Deon588 will do nicely. so you have x = 2 + 3t y = 4  4t and z = 1 + 8t Don't ignore the z component ... rather make it equal to zero 0 = 1 +8t solve for t That fixes the value of t and so you can put back into the x and y equations to get the point as three numbers.

Re: Linear algebra: intersectionThanks again that totally clears it up for me. #7 20121007 19:33:58
