Asked by Arianna

Which equation has intercepts x(1, 0, 0), y(0, -1, 0), and z(0, 0, 2)?


3x-2y+6z=12
2x-2y+z=2
4x-4y+z=4
x-y+2z=4

My answer- 2x-2y+2=2
Answered by Steve
That does not work: 2(1)-2(-1)+2 = 6

Better try again.

4x-4y+z+4?
Answered by Steve
I don't see any choices which work. I suspect a typo.
Answered by Arianna
There was no typo, I had just submitted my quiz and the choice I originally picked was correct.
Answered by Steve
4(1)-4(-1)+2 = 4+4+2 = 10
