    Cartesian equation of plane.

    Determine a scalar equation for the plane that passes through the point (2, 0, −1) and is perpendicular to the line of intersection of the planes
    2x + y z + 5 = 0 and x + y + 2z + 7 = 0.

    What don't you understand? Personally, the phrase "scalar equation for the plane" confused me until I realized the scalar equation for a plane is an equation for a plane in the same form as both 2x + y - z + 5 = 0 and x + y + 2z + 7 = 0.
