Step-by-step explanation:
the x distance from A to B is 3 (from -1 to 2), and the y distance is 15 (from -4 to 11).
the x distance from C to D is also 3 (from 1 to 4), but the y distance is 9 (from 1 to 10).
so, the slopes are different
AB : 15/3 = 5
CD : 9/3 = 3
and the lines are therefore not parallel.
perpendicular slopes are simply inverting y and x in the ratio and flip the sign (from - to + and vice versa). but that is not the case here either (just to start - both slopes are positive).
so, the 2 lines are "neither".

Answer:
B. -3/4.
Step-by-step explanation:
|15 - 12| | - 21 + 9 |
----------- - | -----------|
4 | 8 |
= 3/ 4 - | - 12 / 8 |
= 3/4 - 12/8
= 3/4 - 3/2
= -3/4.
