(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Doesb= [ 2 15 ]^{T}lie in the column of the matrix A

[1 -3]

[2 5]

2. Relevant equations

a basis of CS(U) forms a basis for the corresponding columns for CS(A)

3. The attempt at a solution

I reduced the given matrix into row echelon form and determined its column space. But did not figure out if [2 15]^{T}lies in the column space of A.
