Answer:
Perpendicular
Step-by-step explanation:
Calculate the slopes m of the segments using the slope formula.
m = 
Parallel lines have equal slopes
The product of the slopes of perpendicular lines equals - 1
(x₁, y₁ ) = A(0, 0) and (x₂, y₂ ) = B(e, f)
= 
= 
Repeat with (x₁, y₁ ) = C(0, e) and (x₂, y₂ ) = D(f, 0)
= 
= - 
Thus AB and CD are perpendicular since × - = - 1
(3x − 5) − (4x + 6)
Pretend that there is a 1 in front of the first bracket.
Pretend that there is a -1 in front of the second bracket.
Multiply the first bracket by 1
(1)(3x)=3x, (1)(-5)=-5
Multiply the second bracket by -1
(-1)(4)=-4, (-1)(6)=-6
3x-5-4x-6
3x-4x-5-6 ( combine like terms)
-x-11
Answer: -x-11 or -11-x
