Determine vector and parametric equations for the plane through the point (1, -2, 3) and parallel to the xy-plane

i understand the equations but what is the x-y plane????

what are the x and y equal to?

Flamming...

you need a plane that passes through the point P(1,-2,3) and it is parallel to the plane XY.

to define a plane you need 2 things...

1 one point ...you have it

2 one vector that is perpendicular to the plane..

in your case....the plane XY is parallel to your plane and the vector v(0i+0j+1k) is perpendicular to the plane XY

therefore to define your plane get the point and the vector v and you are ok.... - Mar 30th 2013, 08:45 AMPlatoRe: what is the xy plane

I forgot to mention that the equation of the plane you are looking is z = 3
