I have the following homework
I know the answer is YES and I know the matrix can be written as [imath]\begin{bmatrix} 1 & 0 & -\frac{13}{7}\\ 0 & 1 & -\frac{5}{7}\\ 0 & 0 & 0 \end{bmatrix}[/imath]
which is in reduced Echelon form
However these are my three questions I am curious about...
1. WHY is the answer YES
2. HOW can we see that they have a common point of intersection
3. WHAT does row 3 tell us (since it is all 0's)?
