How to Calculate Line Intersection
What is Line Intersection?
Line intersection finds where two lines meet in 2D or 3D space; useful in geometry and computer graphics.
Step-by-Step Guide
- 1Input two lines (parametric or standard form)
- 2Solve system of equations
- 3Find intersection point or determine parallel/skew
Worked Examples
Input
Line 1: y=2x+1, Line 2: y=-x+4
Result
Intersection: (1, 3)
Common Mistakes to Avoid
- ✕Confusing parametric with standard form
- ✕Not handling 3D case (skew possible)
Frequently Asked Questions
What if lines don't intersect?
Parallel (same slope) or skew in 3D (no intersection).
