Best ResponseYou've already chosen the best response.1?? What is that? I was hoping you would get: x+3y2z8=0 2x+3y7z4=0

Best ResponseYou've already chosen the best response.1They are? What makes you think so? When you eliminated y, didn't that give you a line in the xz plane?

Best ResponseYou've already chosen the best response.1Are you going to buy it, just because it says so? If they are parallel, shouldn't they have the same Normal Vector?

Best ResponseYou've already chosen the best response.0so they're not parallel, they intersect ?

Best ResponseYou've already chosen the best response.13x+9y6z24=0 4x+6y14z8=0 Find a point on one of them. (10,0,1) Prove 3(10) + 9(0)  6(1)  24 = 30 + 0  6  24 = 24  24 = 0 Is it on the other one? 4(10) + 6(0)  14(1)  8 = 40  14  8 = 26  8 = 18 \(\ne 0\) Okay, we just proved that they are NOT coincident. Did you write the problem correctly? If you did, we're done.
