Determine if the Vector is in the Column Space
,
Step 1
Step 2
Step 3
Write the system of equations in matrix form.
Step 4
Find the reduced row echelon form of the matrix.
Perform the row operation on (row ) in order to convert some elements in the row to .
Replace (row ) with the row operation in order to convert some elements in the row to the desired value .
Replace (row ) with the actual values of the elements for the row operation .

Step 5
Use the result matrix to declare the final solutions to the system of equations.
Step 6
The solution is the set of ordered pairs that makes the system true.
Step 7
The vector is in the column space because there is a transformation of the vector that exists. This was determined by solving the system and showing there is a valid result.
