## Homework Statement

1. Find the distance betwwen the parallel palnes:

a) x + y + 2z = 4 and 2x + 2y + 4z +11 = 0

b) ax + by + cz + d1 = 0 and ax + by + cz + d2 = 0

2.Find the equations of the two planes which are parallel to 2x - y + 2z = 5 and 2 unit from it

## Homework Equations

## The Attempt at a Solution

I think i should find any point on one of the plane and using that to find the perpendicular line between two planes which will give the distance between them, but how can i find a point on the plane from the equation given to me?
