Vector Equation Question

  1. Apr 6, 2013 #1
    1. The problem statement, all variables and given/known data
    Question:

    Find the vector equation of the line r = (0,2,-1)+t(1,0,1), t belongs to real numbers, reflected in the plane 2x-y+z-9 = 0.

    I am not sure on how to start solving this question and how do you reflect a line in a plane? What method would you use?

    Thank you for your help!

    Think of the plane as a mirror ... all you need is the reflection of any vector pointing along the line, and one point on the line.

    No worries.
    If you showed us your solution, it would help others stuck in the same place you were.
