Homework Equations
The Attempt at a Solution
Okay so first I translated the line into its parametric equations and then I subbed those into the equation of the plane respectively.
After simplifying you'll find that,
[tex]9t-1 = -1[/tex]
Now my solutions manual states the following,
*NOTE* There is no symbol for not-equivalent in tex, so I'm writing NE
[tex]9t -1 NE -1[/tex]
Why is this so?
Why not let t = 0, and then -1 = -1 and then all will be well in world, no?
What am I missing?
