Hi I have this urgent linear algebra question.

I'm given this here formula $\displaystyle A x = b$

where A = $\displaystyle \left[ \begin{array}{ccc} 1 & 0 & 2 \\ 2 & 1 & 3 \end{array} \right]$ and $\displaystyle \left[ \begin{array}{c} b_1 \\ b_2 \end{array} \right]$ is a vector in R^2.

Then I'm tasked with determing the complete set of solution for T(x) = b.

Do do this I know that I need to solve the following matrix $\displaystyle \left[ \begin{array}{cccc} 1 & 0 & 2 & b_1 \\ 2 & 1 & 3 & b_2 \end{array} \right] $ which can be row-reduced to $\displaystyle \left[ \begin{array}{cccc} 1 & 0 & 2 & {b_1} \\ 2 & 1 & 3 & b_2 - 2b_1 \end{array} \right]$

How do I form the set of solution for the equation T(x) = b from the row-reducet matrix???

Secondly how do I draw this geometricly ??

Sincerely and Best Regards,

Fred
