Question

find an equation of the plane through the point (-1,4,2) that contain the line of intersection of the planes 4x-y+z-2=0 and 2x+y-2z-3=0.

Answer 1

hi so find the equation of the line that is the solution the intersection of those 2 planes and then you got 1 line, and then , take a point on that line and the point given and cross these 2 lines, getting the normal vector and u know the rest from there
