Answer 2

Answer:

Hiii...

This is your answer.

I hope it will help you.

Step-by-step explanation:

Let P (X1,y1) be a point on ax+by+c'=0 so that,

ax+by+c'=0-----------(1)

Now the distance between the two parallel lines is equal to the distance of the line ax+by+c=0 from the point P(X1,y1) which is given by

|ax1+by1+c| (from equation 1)

√a²+b².

= |-c'+c|

√a²+b²
