Why does the solution to Ax=0 lie on a plane, and how to find
the vector which the plane perpendicular to
Write the dot product of (4,4, 2) and (x, y, z) as a matrix multiplication Ax. The matrix A has one row. A = 4 4 2 The solutions to Ax = 0 lie on a plane perpendicular to the vector v = 2 4 , 3 The columns of A are only in 1 -dimensional space. (For numerical answers, just enter the number --- do not spell | out the word; e.g., use "1" or "5", not "one" or "five".) Submit answer
