- Parallel lines never meet. They go up at the same rate, so they have the same slope.
- The slope of is : right , up . So the new line is .
- The point is on the new line: , so and .
- The new line is . Both lines go right , up , so they never meet.
- Traps: is the perpendicular slope, keeps the old line, and copies the point.
