Explanation Given information: The given points are p 1 = [ 1 − 1 2 ] and p 2 = [ 0 − 2 2 ] . Let S = { v 1 , v 2 , v 3 , v 4 } with v 1 = [ − 1 − 3 4 ] , v 2 = [ 0 − 3 1 ] , v 3 = [ 1 − 1 4 ] and v 4 = [ 1 1 − 2 ] . Calculation: Write the points in the matrix form as [ v 1 v 2 v 3 v 4 p 1 p 2 ] . A = [ 1 1 1 1 1 1 − 1 0 1 1 1 0 − 3 − 3 − 1 1 − 1 − 2 4 1 4 − 2 2 2 ] Let R1, R2, R3, and R4 be the row 1, row 2, row 3, and row 4 of the matrix respectively. Perform the row reduction of the matrix as follows: [ 1 1 1 1 1 1 − 1 0 1 1 1 0 − 3 − 3 − 1 1 − 1 − 2 4 1 4 − 2 2 2 ] ~ [ 1 1 1 1 1 1 0 1 2 2 2 1 0 0 2 4 2 1 0 − 3 0 − 6 − 2 − 2 ] R 2 → R 2 + R 1 R3 → R3 + ( 3 ) R 1 R4 → R4 + ( − 4 ) R 1 ~ [ 1 1 1 1 1 1 0 1 2 2 2 1 0 0 1 2 1 1 / 2 0 0 6 0 4 1 ] R3 → ( 1 / 2 ) R3 R4 → R4 + ( 3 ) R2 ~ [ 1 1 1 1 1 1 0 1 2 2 2 1 0 0 1 2 1 1 / 2 0 0 0 − 12 − 2 − 2 ] R4 → R4 + ( − 6 ) R3 ~ [ 1 1 1 1 1 1 0 1 2 2 2 1 0 0 1 2 1 1 / 2 0 0 0 1 1 / 6 1 / 6 ] R4 → ( − 1 / 12 ) R4 Perform row operations to make the values above the diagonal to 0

Solve the linear system of equations attached using Gaussian elimination (not Gauss-Jordan) and back subsitution. Remember that: A matrix is in row echelon form if Any row that consists only of zeros is at the bottom of the matrix. The first non-zero entry in each other row is 1. This entry is called aleading 1. The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.
