Given the plane 2x-3y+7z=4,

a) Find the equation for the line perpendicular to the plane that intersects the plane at the point P=(6,5,1).
b) How far is it from the point (4,-2,3) to the plane?

  • math - ,

    b)The normal equation of the plane
    -4/sqrt(62)=0 62=2^2+(-3)^2+7^2

    The distance=(2*4-3*(-2)+7*3-4)/sqrt(62)=

  • math - ,

    why do you have = signs in part a?
