Permutations are written as nPx where n is the number of total choices possible and x is the number of choices that will be used. This is calculated as nPx = n! / (n-x)!.
Permutations represent the number of ways we can choose x objects from n possibilities where the order of selection matters.

Step-by-step explanation:
two lines are parallel then they have the sane slope
 m1=m2
 m1=m2=6
L2:=Y-y1=m(X-x1)
 =y-(-1)=6(x-2)
 =y+1=6x-12
 y=6x-13 is equation pf parallel lines.
