Question

Does the point (3, 2, -2) lie on the line through C(-1, 4, 5) and D(3, 2, 8)?. In each system, at least one pair of planes are parallel. Describe each
system in words. (hint: no math needed)

a. 2x − y+ 4z = 5
6x − 3y + 12z = 15
4x − 2y + 8z= 10


b. 3x + 2y − z = 8
12x + 8y − 4z= 20
18x + 12y − 6z= −3
