Answer: -1
Step-by-step explanation:
i really don't know but i was taking a test and i guessed it and it was right
The three points give you three equations, which you can solve by your favorite method.
.. 0m +0n +b = 6
.. 1m +0n +b = -3
.. 0m +2n +b = 5
(m, n, b) = (-9, -1/2, 6)
so the equation of the plane can be written as
.. z = -9x -1/2y +6
_____
In standard form, this would be
.. 18x +y +2z = 12
0 is the correct is answer only if x=3
Answer:
62 is the answer.
