So the directions say:

Provide a counterexample to show that each statement is false.

These are the two questions that I'm stuck on:
1. If a line lies in a vertical plane, then the line is vertical
2. If x^2=49, then x=7

I think that the answer to them is this, but I just wanted some verification:
1. If a line is vertical, then the line lies in a vertical plane.
2. x=7 if x^2=49
