Find an equation for the plane through the points (-1, 0, 0), (0, 1, 0), and (0, 0, -1). The equation is: eTextbook and Media Assistance Used Hint Assistance Used Use the three points to find two displacement vectors in the plane. Then take the cross product of the two displacement vectors to find a normal vector to the plane. Finally, use the normal vector you found and one of the given points in the plane to find an equation for the plane containing all three points
