Given the initial and terminal points of a vector, find the component form, the magnitude, and the direction angle. Round the angle to the nearest tenth of a degree.

1. Initial Point: (-1, 7)
Terminal Point: (2, 3)

2. Initial Point: (0, -3)
Terminal Point: (-1, -4)

3. Initial Point: (2, -4)
Terminal Point: (6, 5)
