Expert Answer:

the reqd plane is parallel to 2x-y+3z=-7

so it's perpendicular ro the normal to this plane.

 i.e. it's perpendicular to the line whose d.r. s are 2,-1,3.So in the standard form


so using the point (1,4,-2) as (x1,y1,z1)

we get the equation of the reqd plane as



this is the reqd eqn.
