1. The problem statement, all variables and given/known data My question is how do you use the symmetric equation. For instance I have a question that states: A line L has parametric equations x=4+3t, y=3+4t, z=9-4t. Determine whether or not the points given lie on the line L. points (17, 14, -9). 2. Relevant equations I know that I could set up a symmetric equation like this: x-4/3= y-3/4= z-9/-4 3. The attempt at a solution Do I plug in the points and if they are all equaled to one another does it mean they lay on the line L?
