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

Question

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

Answer 1

3 strikes ...

1. slope AB = (2-0)/(-2-3) = -2/5
slope CD = (4+1)/(-1+3) = 5/2
So perpendicular

2. slope AB = (1+3)/(1-4) = -4/3
slope CD = (1+3)/(2-5) = -4/3
so parallel

3. slope EG = (2-0)/(-3-2) = -2/5
so slope of perpendicular is 5/2

Looks like somebody has some serious review to do.
