Homework Statement


My answer and the answer key in the textbook continue to differ by a constant d, which me and the book have opposites of. For instance, I found the vector to be

y-z=1 but the textbook says y-z= -1

also, I got 7x + y - 11z = -5, but the book says 7x + y - 11z = 5.

Do I have the wrong answer, or is it another form?

It's completely impossible to say, unless you tell us what the question actually is.
 
Both questions ask you to find a plane that goes through a certain point and is either perpendicular or parallel to another plane or vector.
 
That's fine. But what is the actual question?
