1. The problem statement, all variables and given/known data The equation X(t)=A+tL is the parametric equation of a line through the point P:(2,-3,1). The parameter t represents distance from point P, directed so that the I component of L is positive. We know that the line is orthogonal to the plane with the equation 4x-6y+5z=6. Then solve for A and L in vector component form. 2. Relevant equations Standard Vector Calculus equations. 3. The attempt at a solution My problem here is simply understanding what the problem is saying. The t term is throwing me off. Hopefully some of you could shed some light on this.
