Parallel, Perpendicular and Intersecting Lines Formulas
The formulas of useful for parallel, perpendicular and intersecting lines are mentioned below:
- The slope (m) of a line passing through points (x1, y1) and (x2, y2) is given by:
- m = (y2 – y1)/(x2 – x1)
- Two lines are parallel if and only if their slopes are equal. That is, if two lines have slopes m1 and m2
- They are parallel if m1 = m2
- Two lines are perpendicular if the product of their slopes is -1. That is, if two lines have slopes m1 and m2
- They are perpendicular if m1 × m2 = −1.
- Intersecting lines has unique solution
- The intersection point of two lines can be found by solving their equations simultaneously.
