Answer:
Slope of both the lines are same.
Step-by-step explanation:
Line PQ contains points P(x,z) and Q(w,v)
similarly line P'Q' contains points P'(x+a, z+b) and Q'(w+a, v+b)
As we know slope of parallel lines are same, so to prove PQ and P'Q' we will show that these lines have same slope.
Slope of PQ =
Slope of P'Q' =
=
=
So slope of both the lines are same, and both the lines have slope equivalent to
