Homework Statement
Does b = [ 2 15 ]T lie in the column of the matrix A
[1 -3]
[2 5]
Homework Equations
a basis of CS(U) forms a basis for the corresponding columns for CS(A)
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.
