Consider the following statements :

1. The length p of the perpendicular from the origin to the line ax + by + c = 0 satisfies the relation p² = c² / (a² + b²)

2. The length p of the perpendicular from the origin to the line x/a + y/b = 1 satisfies the relation 1/p² = 1/a² + 1/b²

3. The length p of the perpendicular from the origin to the line y = mx + c satisfies the relation 1/p² = 1 + m² + c²

Which of the above is/are correct?
