Mathematics · Three Dimensional Geometry
The point of intersection of the lines represented by vector r = (vector i - 6 vector j + 2 vector k) + t(vector i + 2 vector j + vector k) and vector r = (4 vector j + vector k) + s(2 vector i + vector j + 2 vector k) is:
- 18 vector i + 8 vector j + 9 vector k✓
- 28 vector i + 9 vector j + 8 vector k
- 38 vector i + 8 vector j + 7 vector k
- 48 vector i + 9 vector j + 10 vector k
Correct answer
8 vector i + 8 vector j + 9 vector k
