## Homework Statement

Give examples to describe all 2 × 2 reduced row

echelon matrices

## The Attempt at a Solution

Not sure how to type matrices on here.

I came up with 5 different ones:

0 0

0 0

1 0

0 1

0 1

0 0

1 0

0 0

1 1

0 0

Are there any I'm missing? i can't think of any more than these 5 matrices. Also the problem asks me to give examples to describe all 2x2 RREF matrices. How do I "describe" it or is providing all 5 matrices sufficient>?
