The correct answers are:
___________________________________________________
[A]: "
PQ, where P is at (4, 15) and Q is at (2, 5) " ;
AND:
___________________________________________________
[D]: "
WX, where W is at (3, 1) and X is at (4, 6) " .

Step-by-step explanation:______________________________________________Note: if the slope is the same (i.e., if the "slope" is "5" ), then the segment is "parallel" .
The slope, "m" : m = (y₂ - y₁) / (x₂ - x₁) ;
______________________________________________Consider the answer choices:
______________________________________________ [A]: "(4, 15)" and "(2, 5)" . y₂ = 5 ; y₁ = 15 ; x₂ = 2 ; x₁ = 4 ;
m = (y₂ - y₁) / (x₂ - x₁) = (5 - 15) / (2 - 4) = -10/ -2
= 5 .
So choice [A]: is an answer.________________________________________________ [B]: "(3, 6)" and "(8, 7)" . y₂ = 7 ; y₁ = 6 ; x₂ = 8 ; x₁ = 3 ;
m = (y₂ - y₁) / (x₂ - x₁) = (7 - 6) / (8 - 3)
= 1 /5 ; 1/5

5 ;
So choice [B]: is NOT an answer.
___________________________________________________ [C]: "(6, 4)" and "(11, 3)" . y₂ = 3 ; y₁ = 4 ; x₂ = 11 ; x₁ = 6 ;
m = (y₂ - y₁) / (x₂ - x₁) = (3 - 4) / (11 - 6)
= -1 /5 ; 1/5

5 ;
So choice [C]: is NOT an answer.
___________________________________________________ [D]: "(3, 1)" and "(4, 6)" . y₂ = 6 ; y₁ = 1 ; x₂ = 4 ; x₁ = 3 ;
m = (y₂ - y₁) / (x₂ - x₁) = (6 - 1) / (4 - 3)
= 5 / 1 = 5 ; ;
1/5

5 ;
So choice [D]: is an answer.
