Homework Statement
find the point in this plane where it intersects the z axis (x=y=0).
P = {<x;y;z;> = <1;-1;0;> + a<1;-2;0;> + b<2;0;-1;> , for all a,b}
(by <l;m;n;> i mean to denote a column)
Homework Equations
The Attempt at a Solution
I talked to my TA last friday and he made it seem easy, but I don't remember what he said anymore. I have something that looks like
I set up a matrix that looks like
[<1;-1;0;> <1;-2;0;> <2;0;-1;>] [<1;a;b>] = [<0;0;2;>]
I'm not really sure what to do from here. It says it is asking for a point, does this mean which (a,b) works? What can you help me with?
Thanks in advance.
