Suppose that a 3x3 matrix A has three columns C1, C2, C3 which span the plane given by x + 2y – 5z = 0. Given the column vector (1, 1, 1)² and v = (x, Y, z)* (x, y, a) is the system Av = b consistent? %3D b) How many pivots does the matrix A have? c) Find a specific matrix A whose columns span the plane x + 2y – 5z = 0.

Question
Please help. This problem involves finding the pivots of a linear system. I only need part b. Thank you.
Expert Solution
Step 1
a) yes the linear system is consistent
Since the rank of coefficient matrix is same as the rank of augmented matrix which is 1.
b) there are two pivots are there
We named them as k and l.
