Solved: The solutions (x, y, z) of a single linear
Chapter , Problem 3E(choose chapter or problem)
The solutions (x, y, z) of a single linear equation ax + by + cz = d form a plane in ?3& when a, b, and c are not all zero. Construct sets of three linear equations whose graphs (a) intersect in a single line, (b) intersect in a single point, and (c) have no points in common. Typical graphs are illustrated in the figure.
