Parametric Equation Help?

Question

The equation X (t ) = A + t L is the parametric
equation of a line through the point P : (2, −3, 1) .
The parameter t represents distance from the point
P, directed so that the I component of L is positive.
We know that the line is orthogonal to the plane with
equation 1x + 3y − 2z = −3. Then
A= ___I+ ___J+ ___K
L= ___I+ ___J+ ___K

Is there an formula I can use to find L?

Answer 1

read the components of L from the equation of the plane: <1,3,-2>. A is point P: (2,-3,1)
