Hello! I wanted to know if my answers are right or not? Thanks! :)

1.) Segments AB and CD have the following endpoints. Determine whether the segments are parallel, perpendicular or neither. A (3, 0), B (-2, 2), C (-1, 4), D (-3, -1)

My answer: Parallel

2.) Segments AB and CD have the following endpoints. Determine whether the segments are parallel, perpendicular or neither. A (4, -3), B (1, 1), C (2, 1), D (5, -3)

My answer: Perpendicular

3.) What is the slope of the line perpendicular to Segment EG if the coordinates are (-3, 2) and (2, 0)?

My answer: 2/5
