Hi I have this urgent linear algebra question.

I'm given this here formula

where A = and 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 which can be row-reduced to

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
