Question

The perpendicular distance from (x, y) to the straight line ax + by + c =0​

Answer 1

Answer:

The length of the perpendicular from the origin to the straight line ax + by + c = 0 is |c|√a2+b2. i.e., The perpendicular distance of the line ax + by + c = 0 from the origin c√a2+b2 when c > 0 and - c√a2+b2 when c < 0.
