Answer:
   the lines are perpendicular
Step-by-step explanation:
You can tell something by looking at the differences of coordinates:
   B-A = (6-2, -11-5) = (4, -16) . . . . . Δy/Δx = -16/4 = -4
   D-C = (-1-3, 9-10) = (-4, -1) . . . . .  Δy/Δx = -1/-4 = 1/4
The product of the slopes of these lines is (-4)(1/4) = -1, so ...
   the lines are perpendicular
 
        
             
        
        
        
(3x+1)(4x-1)
3x+4x=7x
1-1=0
So
(3x+1)(4x-1) = 7x
I hope this helped and was right, have a nice day
