## Homework Statement

See figure for problem statement. It asks if a given line lies in a given plane.

## 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?
