1. The problem statement, all variables and given/known data Are these systems of linear equations coincident planes, two parallel planes, or two planes whose intersection is a line. In the latter case, give the parametric equations for the line. X₁+2 X₂-X₃=2 X₁+X₂+X₃=3 2. Relevant equations X₁+2 X₂-X₃=2 X₁+X₂+X₃=3 3. The attempt at a solution X₃=X₁+2 X₂-2=3-X₁-X₂, I set them both equal to X₃and then each other X₂=(5-2X₁)/3 , I am assuming this is the line of intersection. My problem now is that I don't know how to convert to a parametric equation. Could anyone please explain to me how to make a parametric equation.
