# Math Help - determine the base for a plane

1. ## determine the base for a plane

Determine the base for the plane $x-y=0$

But thats a line? i get the base $(1,1)$

How do i get the other base?

regards!

perhaps you are working in 3-dimensional space?

3. ## Re: determine the base for a plane

oh yeah, the question is: Determine bases for the following subspaces of R^3

4. ## Re: determine the base for a plane

so your first basis vector is (1,1,0)....can you figure out the other one? (hint: what values of z make (x,y,z) lie on the plane?)

5. ## Re: determine the base for a plane

would it be (0,0,1)?

Yes , that will do.
