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?
