3x-4y-10=0

6x-8y+5=0

are two parallel lines. How to calculate the distance between them.

The formula for calculating the distance between a line and a point is

[code]

point A(a,b)

line p = Ax+By+C=0

distance d = (|Aa+Bb+C|) / (squareroot(A^2+B^2)

Hoe do i get a point from a line. I know it was very easy but i forgot it.

Thanks!
