In studying for my Linear Algebra test on Monday, I came across a question in my textbook that defines a hyperplane and asks what the dimension of a hyperplane is in Rn. I immediately knew the answer to be n-1, but am having difficulty justifying this claim.(adsbygoogle = window.adsbygoogle || []).push({});

The only thing I can think of now are geometric justifications in the cases of R2 and R3. Using only these, is it valid for me to say the dimension of a hyperplane in Rn is n-1 for any n?
