A=(1,-8,-2) b=(9,2,4)
the plane p contains the point b and is perpendicular to AB. Find the equation of the plane.
Please help- does it mean direction vector AB or A times B? And if it were A times B, would the normal to the plane be A times B or would it be parallel to A and B?
I would really appreciate some help if you can![]()

it is asking you to find the equation of a plane where point B lies on the plane and the vector AB is the normal -

the line segment AB is perpendicular to the plane.

thanks. Does that mean b-a is my normal?
