Determine whether the points lie in a straight line:

1) A (2,4,2), B (3,7,-2), and C (1,3,3)

2) D (0,-5,5), E (1,-2,4), and F (3,4,2)

I'm not sure what method I need to use to show that they are or are not in a straight line. I know that the three points in a are not in a line but those in group b are in a line.

1) A (2,4,2), B (3,7,-2), and C (1,3,3)

2) D (0,-5,5), E (1,-2,4), and F (3,4,2)
