Determine if

$a.H=\{\frac{x,y}{y}=3x-1\}$ is a subspace of R2

$b.H=\{at+\frac{b}{b}=8a\}$ is a subspace of P1

You can still ask an expert for help

Question that asks me to describe a vector x that satisfies:

$T(x)=\left[\begin{array}{c}-8\\ 9\\ 2\end{array}\right]$

Gven matrix:

$A=\left[\begin{array}{ccc}1& 3& 1\\ -2& 1& 5\\ 0& 2& 2\end{array}\right]$

also aware that T(x) = Ax. I would like to know the general process for finding what x is when given the output vector and a matrix to be multiplied by the unknown input vector x.

$\left[\begin{array}{cccc}1& 0& -2& 0\\ 0& 1& 1& 0\\ 0& 0& 0& 1\end{array}\right]$

I have tried putting the augmented matrix in reduced row echelon form above, but I am not sure where to go from there.
